Elena Demikhovsky 264fb0217e The VPSHUFB 256-bit instruction may be generated when one of input vector is undefined or zeroinitializer. 
I've added the "zeroinitializer" case in this patch.

Benjamin Kramer 8dd0edc7b1 c bindings: revert LLVMConstInlineAsm to always use the default asm dialect. 
- The C API should be stable
- InlineAsm::AsmDialect is not exposed to C
- The function didn't match the prototype so this was unreachable code

Evgeniy Stepanov c9cdb96188 GTest on Android needs a custom tmpdir path.

Evgeniy Stepanov c9cde48f3a Wrong crtbegin/crtend pair used for PIE on Android. 
Android uses the same flavour of crt*.o for PIE and non-PIE executables, and a
different one for DSOs. GNU/Linux, on the other hand, uses one set of crt*.o
for non-PIE executables, and another for both PIE executables and DSOs.

Ted Kremenek 3d92699d3c Take another crack at stabilizing the emission order of analyzer 
diagnostics without using FoldingSetNodeIDs.  This is done
by doing a complete recursive comparison of the PathDiagnostics.

Note that the previous method of comparing FoldingSetNodeIDs did
not end up relying on unstable things such as pointer addresses, so
I suspect this may still have some issues on various buildbots because
I'm not sure if the true source of non-determinism has been eliminated.
The tests pass for me, so the only way to know is to commit this change
and see what happens.

Benjamin Kramer 851c941b8b LiveVariables: Compute a set of defs and kills to speed up updating LV during critical edge splitting. 
Previously we checked if the register is def'd in a block via the def/use list a
nd walked the list of kills to check if the register is killed in a block. Both
of these checks can be made much cheaper by walking the block first and
recording all defs and kills.

This reduces the compile time of the test case from PR13651 from 40s to 15s at
-O2. The compile time is still dominated by LV updating but now the main culprit
is SparseBitVector's slowness.
