d422190c0f Add AVX2 VEXTRACTI128 and VINSERTI128 instructions. Fix VPERM2I128 to be qualified with HasAVX2 instead of HasAVX. Mark VINSERTF128 and VEXTRACTF128 as never having side effects.

806ffd8918 Add support for passing i1, i8, and i16 call parameters. Also, be sure to 
zero-extend the constant integer encoding.  Test case provides testing for
both call parameters and materialization of i1, i8, and i16 types.

4c8932e3b8 Add an option to pad an uleb128 to MCObjectWriter and remove the uleb128 encoding from the DWARF asm printer. 
As a side effect we now print dwarf ulebs with .ascii directives.

1478b657c8 Enhanced vzeroupper insertion pass that avoids inserting vzeroupper where it is unnecessary through local analysis. Patch from Bruno Cardoso Lopes, with some additional changes. 
I'm going to wait for any review comments and perform some additional testing before turning this on by default.

a5f382da8b Reapply r143206, with fixes. Disallow physical register lifetimes 
across calls, and only check for nested dependences on the special
call-sequence-resource register.

4902705b5f DeadStoreElimination can now trim the size of a store if the end of it is dead. 
Only currently done if the later store is writing to a power of 2 address or 
has the same alignment as the earlier store as then its likely to not break up
large stores into smaller ones

ac9fd95057 Fix the issue that r143552 was trying to address the _right_ way. One-register lists are legal on LDM/STM instructions, but we should not print the PUSH/POP aliases when they appear. This fixes round tripping on this instruction.

3c1e831108 Rewrite LinearFunctionTestReplace to handle pointer-type IVs. 
We've been hitting asserts in this code due to the many supported
combintions of modes (iv-rewrite/no-iv-rewrite) and IV types. This
second rewrite of the code attempts to deal with these cases systematically.

b5dc88b394 Fixed a bug in the code to create a dwarf file and directory table entires when 
it is separating the directory part from the basename of the FileName.  Noticed 
that this:

  .file 1 "dir/foo"

when assembled got the two parts switched.  Using the Mac OS X dwarfdump tool
it can be seen easily:

% dwarfdump -a a.out
include_directories[  1] = 'foo'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 dir
...

Which should be:
...
include_directories[  1] = 'dir'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 foo
