Jim Grosbach 199ab90946 ARM assembly parsing needs to be paranoid about negative immediates. 
Make sure to treat immediates as unsigned when doing relative comparisons.

Jim Grosbach 0b0298302c ARM assembly 'cmp lr, #0' should not encode using 'cmn'. 
The CMP->CMN alias was matching for an immediate of zero when it
should only match for negative values.

Eli Bendersky f33086052d Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnu 
* Removed test/lib/llvm.exp - it is no longer needed 
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
  left in the test suite so this code is no longer required. test/lit.cfg is
  now much shorter and clearer 
* Removed a lot of duplicate code in lit.local.cfg files that need access to
  the root configuration, by adding a "root" attribute to the TestingConfig
  object. This attribute is dynamically computed to provide the same
  information as was previously provided by the custom getRoot functions. 
* Documented the config.root attribute in docs/CommandGuide/lit.pod

Jim Grosbach 905686a82a ARM ldm/stm register lists can be out of order. 
It's not a good style idea, as the registers will be laid down in memory in
numerical order, not the order they're in the list, but it's legal. vldm/vstm
are stricter.

Jim Grosbach 7b811d30d9 ARM BL/BLX instruction fixups should use relocations. 
We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the
relocation to do that, so we need to be careful about being too clever.

To enable this for ARM mode, split the BL/BLX fixup kind off from the
unconditional-branch fixups.

For bit patterns that aren't representable using the 8-bit floating point

'vmov.f32 Vd, #0.0'.
