37142b6930 [fast-isel] Add X86FastIsel::FastLowerArguments to handle functions with 6 or 
fewer scalar integer (i32 or i64) arguments. It completely eliminates the need
for SDISel for trivial functions.

Also, add the new llc -fast-isel-abort-args option, which is similar to
-fast-isel-abort option, but for formal argument lowering.

37f247b8d8 Move the eliminateCallFramePseudoInstr method from TargetRegisterInfo 
to TargetFrameLowering, where it belongs. Incidentally, this allows us
to delete some duplicated (and slightly different!) code in TRI.

There are potentially other layering problems that can be cleaned up
as a result, or in a similar manner.

The refactoring was OK'd by Anton Korobeynikov on llvmdev.

Note: this touches the target interfaces, so out-of-tree targets may
be affected.

79457c8f90 getX86SubSuperRegister has a special mode with High=true for i64 which 
exists solely to enable it to call itself for i8 with some registers.
The proposed patch simplifies the function somewhat to make the High
bit only meaningful for the i8 mode, which makes sense. No functional
difference (getX86SubSuperRegister is not getting called from anywhere
outside with i64 and High=true).

233487d8a2 Update TargetLowering ivars for name policy. 
http://llvm.org/docs/CodingStandards.html#name-types-functions-variables-and-enumerators-properly

ivars should be camel-case and start with an upper-case letter. A few in
TargetLowering were starting with a lower-case letter.

No functional change intended.

0886fb4d55 I optimized the following patterns: 
sext <4 x i1> to <4 x i64>
 sext <4 x i8> to <4 x i64>
 sext <4 x i16> to <4 x i64>
 
I'm running Combine on SIGN_EXTEND_IN_REG and revert SEXT patterns:
 (sext_in_reg (v4i64 anyext (v4i32 x )), ExtraVT) -> (v4i64 sext (v4i32 sext_in_reg (v4i32 x , ExtraVT)))
 
 The sext_in_reg (v4i32 x) may be lowered to shl+sar operations.
 The "sar" does not exist on 64-bit operation, so lowering sext_in_reg (v4i64 x) has no vector solution.

I also added a cost of this operations to the AVX costs table.

2be41be7b9 [ms-inline asm] Force the use of a base pointer if the MachineFunction includes 
MS-style inline assembly.

This is a follow-on to r175334.  Forcing a FP to be emitted doesn't ensure it
will be used.  Therefore, force the base pointer as well.  We now treat MS
inline assembly in the same way we treat functions with dynamic stack
realignment and VLAs.  This guarantees the BP will be used to reference 
parameters and locals.

1062ec80b5 [ms-inline asm] Do not omit the frame pointer if we have ms-inline assembly. 
If the frame pointer is omitted, and any stack changes occur in the inline
assembly, e.g.: "pusha", then any C local variable or C argument references
will be incorrect.  

I pass no judgement on anyone who would do such a thing. ;)

cc20bdf27b Use the 'target-features' and 'target-cpu' attributes to reset the subtarget features. 
If two functions require different features (e.g., `-mno-sse' vs. `-msse') then
we want to honor that, especially during LTO. We can do that by resetting the
subtarget's features depending upon the 'target-feature' attribute.

50b6c2a0e2 Don't make assumptions about the mangling of static functions in extern "C" 
blocks. We still don't have consensus if we should try to change clang or
the standard, but llvm should work with compilers that implement the current
standard and mangle those functions.
