Kevin Enderby 168ffb36a5 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.

Kevin Enderby 136d6746c5 Fixed the arm disassembly of invalid BFI instructions to not build a bad MCInst

Eli Bendersky e66c51d111 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.

Jim Grosbach 4739f2eb19 ARM: Better disassembly for pc-relative LDR.
When the operand is a plain immediate rather than a label, print it
as [pc, #imm] like we do for the Thumb2 wide encoding variant.

Kevin Enderby 6fd9624843 Fix ARM's b.w instruction for thumb 2 and the encoding T4. The branch target
is 24 bits not 20 and the decoding needed to correctly handle converting the
J1 and J2 bits to their I1 and I2 values to reconstruct the displacement.

Kevin Enderby 62183c4e18 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.

Chandler Carruth ff123d5c63 Fix the remaining TCL-style quotes found in the testsuite. This is
another mechanical change accomplished though the power of terrible Perl
scripts.

I have manually switched some "s to 's to make escaping simpler.

While I started this to fix tests that aren't run in all configurations,
the massive number of tests is due to a really frustrating fragility of
our testing infrastructure: things like 'grep -v', 'not grep', and
'expected failures' can mask broken tests all too easily.

Essentially, I'm deeply disturbed that I can change the testsuite so
radically without causing any change in results for most platforms. =/

Chandler Carruth 5da53436d5 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.

Chandler Carruth a5a29f970e 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. ;]

Benjamin Kramer ef479ea854 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.
