Bruno Cardoso Lopes f15dfe5818 The VPERM2F128 is a AVX instruction which permutes between two 256-bit 
vectors. It operates on 128-bit elements instead of regular scalar
types. Recognize shuffles that are suitable for VPERM2F128 and teach
the x86 legalizer how to handle them.

Jordy Rose add45b78dd [analyzer] Nitpicks on Olaf's patch, which I meant to e-mail but then didn't in 
time. One is cleanup, the other is me being OCD about enum group nesting.

Greg Clayton 7e9b1fd045 We were leaking a stack frame in StackFrameList in Thread.cpp which could 
cause extra shared pointer references to one or more modules to be leaked.
This would cause many object files to stay around the life of LLDB, so after
a recompile and rexecution, we would keep adding more and more memory. After
fixing the leak, we found many cases where leaked stack frames were still
being used and causing crashes in the test suite. These are now all resolved.

Anna Zaks c94894fbc2 MacOSKeychainAPIChecker: There is no need to use SymbolMetadata to represent the allocated data symbol, we can just use the symbol corresponding to the SymbolicRegion. This simplifies tracking of the symbol, for example, SymbolMetadata needs to go through extra hoops to stay alive. 
Make AllocationState internal to the MacOSKeychainAPIChecker class.

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.
