Evan Cheng f192ca0761 Refine r141689 with a tri-state variable.
Also teach MachineLICM to avoid "speculation" when register pressure is high.

Johnny Chen 8a7f3f5bac Add a more generic stepping benchmark, which uses the '-k' option of the test driver
to be able to specify the runhook(s) to bring the debug session to a certain state
before running the benchmarking logic.  An example,

./dotest.py -v -t +b -k 'process attach -n Mail' -k 'thread backtrace all' -p TestRunHooksThenSteppings.py

spawns lldb, attaches to the 'Mail' application, does a backtrace for all threads, and then
runs the benchmark to step the inferior multiple times.

John McCall 50a2c2c19d Catch placeholder types in DefaultLvalueConversion
and DefaultFunctionArrayLvalueConversion.  To prevent
significant regression for should-this-be-a-call fixits,
and to repair some such regression from the introduction of
bound member placeholders, make those placeholder checks
try to build calls appropriately.  Harden the build-a-call
logic while we're at it.

Eric Christopher 498b7fd7fe Start handling debug line and scope information better:
Migrate most of the location setting within the larger API in CGDebugInfo and
update a lot of callers.
Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
and replace it with DILexicalBlockFile usage.

Eric Christopher 6647b83087 Add a new wrapper node for a DILexicalBlock that encapsulates it and a
file. Since it should only be used when necessary propagate it through
the backend code generation and tweak testcases accordingly.

This helps with code like in clang's test/CodeGen/debug-info-line.c where
we have multiple #line directives within a single lexical block and want
to generate only a single block that contains each file change.

Bill Wendling 579ff6c39c N.B. This is with the new EH scheme:
The blocks with invokes have branches to the dispatch block, because that more
correctly models the behavior of the CFG. The dispatch of course has edges to
the landing pads. Those landing pads could contain invokes, which then have
branches back to the dispatch. This creates a loop. The machine LICM pass looks
at this loop and thinks it can hoist elements out of it. But because the
dispatch is an alternate entry point into the program, the hoisted instructions
won't be executed.

I wasn't able to get a testcase which was small and could reproduce all of the
time. The function_try_block.cpp in llvm-test was where this showed up.

Cameron Zwarich 1a761dcfbd Fix PR11106 by correcting a typo that has been in the code for over a year. This
would have never worked, since the element type of a vector type is never a
vector type. Also fix the conditional to be more direct in checking whether
EltTy is a vector type.

Daniel Dunbar 0f41eee2a0 Driver: Add support for a new -nostdlibinc option.
- This disables the system include directories, but not the compiler builtin
   directories. Useful for projects that want to use things like the intrinsic
   headers, but are otherwise freestanding.

 - I'm willing to reconsider the option naming, I also considered providing an
   explicit -builtinc (which would match -nobuiltininc), but this is more
   consistent with existing options.
