Chad Rosier 925c9b499e [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. ;)

Bill Wendling a060d0efd8 Reinitialize the ivars in the subtarget. 
When we're recalculating the feature set of the subtarget, we need to have the
ivars in their initial state.

Bill Wendling aef9c37c65 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.

Rafael Espindola 91cbcbb909 Give these callbacks hidden visibility. It is better to not export them more 
than we need to and some ELF linkers complain about directly accessing symbols
with default visibility.

Rafael Espindola 9b7d4004bc 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.

Benjamin Kramer 8e2637e2b0 X86: Disable generation of rep;movsl when %esi is used as a base pointer. 
This happens when there is both stack realignment and a dynamic alloca in the
function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the
base pointer and the next register spill will write into oblivion.

Fixes PR15249 and unbreaks firefox on i386/freebsd. Mozilla uses dynamic allocas
and freebsd a 4 byte stack alignment.

Eli Bendersky ef4558abd3 This is a follow-up on r174446, now taking Atom processors into 
account. Atoms use LEA for updating SP in prologs/epilogs, and the
exact LEA opcode depends on the data model.

Also reapplying the test case which was added and then reverted
(because of Atom failures), this time specifying explicitly the CPU in
addition to the triple. The test case now checks all variations (data
mode, cpu Atom vs. Core).

Eli Bendersky 44a40ca143 Make sure the correct opcodes are used to SUB and ADD the stack 
pointer in function prologs/epilogs. The opcodes should depend on the
data model (LP64 vs. ILP32) rather than the architecture bit-ness.

Evgeniy Stepanov 1f5a71492d More MSan/ASan annotations. 
This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains
fixes for 2 issues:

- X86JIT reads return address from stack, which MSan does not know is
  initialized.
- bugpoint tests run binaries with RLIMIT_AS. This does not work with certain
  Sanitizers.

We are no longer including config.h in Compiler.h with this change.

David Sehr 8114a7a651 Two changes relevant to LEA and x32: 
1) allows the use of RIP-relative addressing in 32-bit LEA instructions under
   x86-64 (ILP32 and LP64)
2) separates the size of address registers in 64-bit LEA instructions from
   control by ILP32/LP64.
