7af95b6c84 Fix suffix handling for parsing and printing of cvtsi2ss, cvtsi2sd, cvtss2si, cvttss2si, cvtsd2si, and cvttsd2si to match gas behavior.
cvtsi2* should parse with an 'l' or 'q' suffix or no suffix at all. No suffix should be treated the same as 'l' suffix. Printing should always print a suffix. Previously we didn't parse or print an 'l' suffix.
cvtt*2si/cvt*2si should parse with an 'l' or 'q' suffix or not suffix at all. No suffix should use the destination register size to choose encoding. Printing should not print a suffix.

Original 'l' suffix issue with cvtsi2* pointed out by Michael Kuperstein.

94941df94f Added a option to the disassembler to print immediates as hex.
This is for the lldb team so most of but not all of the values are
to be printed as hex with this option.  Some small values like the
scale in an X86 address were requested to printed in decimal
without the leading 0x.

There may be some tweaks need to places that may still be in
decimal that they want in hex.  Specially for arm.  I made my best
guess.  Any tweaks from here should be simple.

I also did the best I know now with help from the C++ gurus
creating the cleanest formatImm() utility function and containing
the changes.  But if someone has a better idea to make something
cleaner I'm all ears and game for changing the implementation.

e5d04ab064 Make this test less sensitive.
It currently assumes register numbering and any harmless change in the X86
register naming makes it fail. It's enough to match the register names.

0f6b703b72 Add support for annotated disassembly output for X86 and arm.
Per the October 12, 2012 Proposal for annotated disassembly output sent out by
Jim Grosbach this set of changes implements this for X86 and arm.  The llvm-mc
tool now has a -mdis option to produced the marked up disassembly and a couple
of small example test cases have been added.

d200829a4f Convert the uses of '|&' to use '2>&1 |' instead, which works on old
versions of Bash. In addition, I can back out the change to the lit
built-in shell test runner to support this.

This should fix the majority of fallout on Darwin, but I suspect there
will be a few straggling issues.

8a358b3669 Convert all tests using TCL-style quoting to use shell-style quoting.
This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.

Finally, the test suite runs 33% faster on Linux now. ;]

63bf58865a X86: add more GATHER intrinsics in LLVM
Corrected type for index of llvm.x86.avx2.gather.d.pd.256
  from 256-bit to 128-bit.

0c823ae0ed Add intrinsics, code gen, assembler and disassembler support for the SSE4a extrq and insertq instructions.
This required light surgery on the assembler and disassembler
because the instructions use an uncommon encoding. They are
the only two instructions in x86 that use register operands
and two immediates.

9e62efdf5f Add -disassemble support for -show-inst and -show-encode capability llvm-mc. Also refactor so all MC paraphernalia are created once for all uses as much as possible.
The test change is to account for the fact that the default disassembler behaviour has changed with regards to specifying the assembly syntax to use.

3ef88c1833 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
