This change uses a fixed known offset for the Linux i386 DR0 register.
This change also undoes the 32-bit wordsize change from r169645 that
revolved around being 32-bit/64-bit friendly in
WriteRegOperation::Execute within the Linux ProcessMonitor.cpp. I ran
all the tests on x86_64 Linux with no failures. I also ran some simple
tests with 32-bit Linux exe on x86_64 host and 32-bit linux exe on
i686 32-bit host and these worked fine.
Note (from Todd): the UserData struct in the Linux i386 register
context (only used by Linux i386 host running Linux 32-bit inferior)
is out of sync with what shows up in the sys/user.h for an 32-bit
Linux build (per an earlier change of mine to make it look more like
x86_64 host running x86 exe). I think we should (1) make i386 Linux
targets run using the same register context (and correct ones) on i386
and x86_64 linux hosts if that is possible, and (2) we could use some
tests around the register handling, particularly to verify things like
DR0 registers are in the right spots on host/target combos that we can
verify vs. known correct values.

The following two tests showed up as XFAIL even though they should
always be skipped on Linux, due to the @unittest2.expectedFailure
annotation appearing above the @dsym_test annotation:
TestObjCNewSyntax.ObjCNewSyntaxTestCase.test_expr_with_dsym
TestBlocks.BlocksTestCase.test_expr_with_dsym.
For those two, I simply moved the @dsym_test annotation to the top so
that it would be marked for skip ahead of being marked for XFAIL.
TestObjCNewSyntax.ObjCNewSyntaxTestCase.test_expr_with_dwarf I marked
as @skipIfLinux since my understanding is that isn't a valid test to
run on Linux. So rather than categorize as a fail (i.e. something
wrong to be fixed), just skip it. (My recent changes to Linux tests
have been following that model: if it could never work, skip; if it's
broken, mark XFAIL so we can easily track, fix, notice the fix and
adjust accordingly).
TestDeadStrip.DeadStripTestCase.test_with_dwarf I had previously
marked as XFAIL but this would never work on Linux with the current
linker AFAICT. Marked it as skip.

read during materialization. First of all, report
if we can't read the data for some reason. Second,
consult the ValueObject's error and report that if
there's some problem.

This seems a little more straightforward and is equivalent to r201457
for ELF core files. A case for FreeBSD i386 is also added (it was
incorrectly using the 64-bit register context and corrupting mememory).
Better (user-facing) error handling is still needed.

This change adds a missing include path to the
ObjC LanguageRuntime path to the MacOSX SystemRuntime
plugin's Makefile.
It also adds the panel and curses library to the liblldb
shared library linkage step.

I carefully reviewed exactly how the IOHandlers interact and found places where we weren't properly controlling things. There should be no overlapping prompts and all output should now come out in a controlled fashion.

I suspect I may have misrun the test previously for check-in
r202456 re: pr15258. This test fails consistently on my end.
I changed the test to expected failure on Linux.
llvm-svn: 202517
TestRegisterVariables.test_with_dwarf_and_run_command was being
skipped on Linux due to issues with clang. I converted it to a
@expectedFailureClang and no longer skip on Linux.
llvm-svn: 202515
TestConstVariables.py was disabled on Linux and marked as
unconditional expected failure. This change removes the Linux disable
and makes the expected failure conditional on using clang. The test
runs fine on gcc-built lldb.

This test passed 50 out of 50 times for me on Unbuntu 12.04 LTS x86_64

On TOT lldb svn r202507, I found several of the tests disabled within
TestConcurrentEvents.py to run fine, and several of them to fail 100%
of the time on my system (25 out of 25 times).
This changes the following tests for Linux:
Enables (these all work consistently):
* test_many_watchpoints_dwarf
* test_signal_watch_break_dwarf (line 250)
* test_signal_watch_break_dwarf (line 260 - same named test?)
* test_crash_with_watchpoint_dwarf
* test_crash_with_watchpoint_breakpoint_signal_dwarf
* test_delayed_crash_with_breakpoint_watchpoint_dwarf
Marks as expected failure (these all fail consistently):
* test_many_watchpoints_dwarf
* test_watch_break_dwarf
* test_delay_watch_break_dwarf
* test_watch_break_dwarf_delay
* test_signal_watch_dwarf
* test_delay_signal_watch_dwarf
* test_signal_delay_watch_dwarf
* test_two_breakpoints_one_watchpoint_dwarf
* test_breakpoints_delayed_breakpoint_one_watchpoint_dwarf
* test_two_watchpoint_threads_dwarf
* test_watchpoint_with_delay_watchpoint_threads_dwarf
* test_two_watchpoints_one_breakpoint_dwarf
* test_two_watchpoints_one_delay_breakpoint_dwarf
* test_watchpoint_delay_watchpoint_one_breakpoint_dwarf
* test_two_watchpoints_one_signal_dwarf
* test_signal_watch_break_dwarf

Previously this was marked as skipped. I tried running it 10 times in
a row and it failed every time. Switched it to XFAIL.

Also remove SetStopOthers from the ThreadPlanCallFunction, because if the value you have doesn't match what is
in the EvaluateExpressionOptions the plan was passed when created it won't work correctly.

1 - There were some outdated options being passed to clang
2 - There were some bad paths being passed as options
3 - The path to the main.cpp file ("/tmp/main.cpp") was wrong when the tests were being run, now we create a temp file
4 - Added a new ActionType::eNone to do nothing (no continue, step, or kill)

This change fixes up issues with specifying the size of the i386
register infos for FPU registers. The bug was that for the i386
register context, the size of the FPU registers were still being
computed based on the x86_64 FXSAVE structure.
This change permits the FPR_SIZE macro to optionally be defined
outside of RegisterInfos_i386.h, which RegisterContextLinux_i386.cpp
does properly. It redefines the FPR_i386 structure with all the
accessible parts that RegisterInfos_i386.h wants to see, which we had
not done before when we made the overall size of the structure
properly sized a recently.
This change also modifies POSIXThread to create a
RegisterContextLinux_i386 only when the host is 32-bit; otherwise, it
uses the RegisterContextLinux_x86_64, which works properly for 32-bit
and 64-bit inferiors on a 64-bit host.
I tested this debugging a Linux x86 exe on an x86 host (Ubuntu 13.10
x86), and debugging a Linux x86 exe and a Linux x86-64 exe on an
x86-64 host (Ubuntu 12.04 LTS). Those cases all worked.
Thanks to Matthew Gardiner who discoverd may key insights into
tracking down the issue. The motivation for this change and some of
the code originates from him via this thread:

We now write a 'q' to indicate to exit the IOHandlerProcessSTDIO::Run(), and a 'i' to interrupt the process. This should make this code safer to use in a signal handler function.

This fix changes thee x86 32-bit floating point register area to be
the proper size independent of the host platform.
Note as of this change list, this register context is not yet used
since selecting it exposes issues with watchpoint assertions.
