2f2c3bf31f Simplify the handling of pcrel relocations on ELF. Now we do the right thing 
for all symbol differences and can drop the old EmitPCRelSymbolValue
method.

This also make getExprForFDESymbol on ELF equal to the one on MachO, and it
can be made non-virtual.

7901d3790e Add all the plumbing needed for MC to expand cfi to the old tables in 
the final assembly. It is the same technique used when targeting
assemblers that don't support .loc.

b1b2ee909c ptx: fix parameter ordering 
This patch depends on the prior fix r129908 that changes to use std::find,
rather than std::binary_search, on unordered array.

dc1965a16c PTX: Add intrinsics to list of built-in intrinsics, which allows them to be 
used by Clang.  To help Clang integration, the PTX target has been split
     into two targets: ptx32 and ptx64, depending on the desired pointer size.

- Add GCCBuiltin class to all intrinsics
- Split PTX target into ptx32 and ptx64

2e7bb6da4c Extend initial support for primitive types in PTX backend 
- Allow i16, i32, i64, float, and double types, using the native .u16,
  .u32, .u64, .f32, and .f64 PTX types.
- Allow loading/storing of all primitive types.
- Allow primitive types to be passed as parameters.
- Allow selection of PTX Version and Shader Model as sub-target attributes.
- Merge integer/floating-point test cases for load/store.
- Use .u32 instead of .s32 to conform to output from NVidia nvcc compiler.

- Allow parameters, return values, and global variable declarations
  to accept the float type.
- Add appropriate test cases.

59c8ae34f7 Use explicit add_subdirectory's for LLVM target sublibraries instead 
of testing for its presence at cmake time.
