22378fd664 ARM assembly aliases for two-operand V[R]SHR instructions. 
rdar://11189467

541b2a4aa3 In MemoryBuffer::getOpenFile() make sure that the buffer is null-terminated if 
the caller requested a null-terminated one.

When mapping the file there could be a racing issue that resulted in the file being larger
than the FileSize passed by the caller. We already have an assertion
for this in MemoryBuffer::init() but have a runtime guarantee that
the buffer will be null-terminated, so do a copy that adds a null-terminator.

Protects against crash of rdar://11161822.

b657a90929 ARM assembly parsing for 'msr' plain 'cpsr' operand. 
Plain 'cpsr' is an alias for 'cpsr_fc'.

9243c4f7c5 Pass the right sign to TLI->isLegalICmpImmediate. 
LSR can fold three addressing modes into its ICmpZero node:

  ICmpZero BaseReg + Offset      => ICmp BaseReg, -Offset
  ICmpZero -1*ScaleReg + Offset  => ICmp ScaleReg, Offset
  ICmpZero BaseReg + -1*ScaleReg => ICmp BaseReg, ScaleReg

The first two cases are only used if TLI->isLegalICmpImmediate() likes
the offset.

Make sure the right Offset sign is passed to this method in the second
case. The ARM version is not symmetric.

to simplify cases like the one in the included testcase.

9dbb018b36 Fix an issue in SimplifySetCC() specific to vector comparisons. 
When folding X == X we need to check getBooleanContents() to determine if the
result is a vector of ones or a vector of negative ones. 

I tried creating a test case, but the problem seems to only be exposed on a
much older version of clang (around r144500).
