Bill Wendling fae1475823 Initial commit of the 'landingpad' instruction. 
This implements the 'landingpad' instruction. It's used to indicate that a basic
block is a landing pad. There are several restrictions on its use (see
LangRef.html for more detail). These restrictions allow the exception handling
code to gather the information it needs in a much more sane way.

This patch has the definition, implementation, C interface, parsing, and bitcode
support in it.

Johnny Chen 9f4f5d94cd Add TestInferiorChanged.py to test that lldb reloads the inferior after it was changed during the debug session. 
First, main.c causes a crash, the inferior then gets re-built with main2.c which is not crashing.

Add Base.cleanup(self, dictionary=None) for platform specfic way to do cleanup after build.
This plugin method is used by the above test case to cleanup the main.c build before rebuild for main2.c.

Enrico Granata 68eb4bb421 Added an error message when the user tries to add a filter when a synthetic provider for the same type is already defined in the same category 
The converse is also true: an error is shown when the user tries to add a synthetic provider to a category that already has a filter for the same type

Akira Hatanaka 7bd6e6ebef When constant double 0.0 is lowered, make sure 0 is copied directly from an 
integer register to a floating point register. It is not valid to interpret
the value of a floating pointer register as part of a double precision
floating point value after a single precision floating point computational
or move instruction stores its result to the register.

- In the test case, the following code is generated before this patch is
  applied:
mtc1  $zero, $f2    ; unformatted copy to $f2
mov.s $f0, $f2      ; $f0 is in single format
sdc1  $f12, 0($sp)
mov.s $f1, $f2      ; $f1 is in single format
c.eq.d  $f12, $f0   ; $f0 cannot be interpreted as double

- The following code is generated after this patch is applied:
mtc1  $zero, $f0    ; unformatted copy to $f0
mtc1  $zero, $f1    ; unformatted copy to $f1
c.eq.d  $f12, $f0   ; $f0 can be interpreted as double

Bhanu Chetlapalli and Chris Dearman at MIPS technologies reported this bug and
provided the test case.

Greg Clayton 5113dc8e54 Fixed some issues with parsing C++ methods where our detection 
was failing if the DWARF was laid out in a certain way. The way
we detect C++ classes is now more robust so that a class method
can be defined outside of the class and refer to a definition inside
the class with a DW_AT_specification or DW_AT_abstract_origin attribute.

Fixed a case in Thread.cpp where we were looking up info in the frame
when we didn't need to. This was from some changes to support external
editors. Now the info is only looked up if needed.
