5b25503aab Fix PR8445: a block with no predecessors may be the entry block, in which case 
it isn't unreachable and should not be zapped.  The check for the entry block
was missing in one case: a block containing a unwind instruction.  While there,
do some small cleanups: "M" is not a great name for a Function* (it would be
more appropriate for a Module*), change it to "Fn"; use Fn in more places.

c63105a064 More tweaks to X86 instructions to allow the 'w' suffix in places it makes 
sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler allows
for these instructions.  Also added the missing flex (without the wait prefix)
and ud2a as an alias to ud2 (still to add ud2b).

c50372298d Major update of the MicroBlaze backend. The new features are: 
1. A delay slot filler that searches for valid instructions
       to fill the delay slot with. Previously NOPs would always
       be inserted into delay slots.
    2. Support for MC based instruction printer added.
    3. Support for MC based machine code generation and ELF
       file generation. ELF file generation does not yet
       completely work as much of the ELF support infrastructure
       is still x86/x86-64 specific.
    4. General clean up of the MBlaze backend code. Much of the
       tablegen code has been cleanup and simplified.

Bug Fixes:
    1. Removed duplicate periods from subtarget feature descriptions.
    2. Many of the instructions had bad machine code information
       in the tablegen files. Much of this has been fixed.

9a06e4c7c8 More accurate estimate / tracking of register pressure. 
- Initial register pressure in the loop should be all the live defs into the
  loop. Not just those from loop preheader which is often empty.
- When an instruction is hoisted, update register pressure from loop preheader
  to the original BB.
- Treat only use of a virtual register as kill since the code is still SSA.

ccbc75257a Fixing r116753 r116756 r116777 
The failures in r116753 r116756 were caused by a python issue -
Python likes to append 'L' suffix to stringified numbers if the number
is larger than a machine int. Unfortunately, this causes a divergence of
behavior between 32 and 64 bit python versions.

I re-crafted elf-dump/common_dump to take care of these issues by:

1. always printing 0x (makes for easy sed/regex)
2. always print fixed length (exactly 2 + numBits/4 digits long)
   by mod ((2^numBits) - 1)
3. left-padded with '0'

There is a residual common routine that is also used by
macho-dump (dataToHex) , so I left the 'section_data' test values alone.

9c3f6f486e - Add a hook for target to determine whether an instruction def is 
"long latency" enough to hoist even if it may increase spilling. Reloading
  a value from spill slot is often cheaper than performing an expensive
  computation in the loop. For X86, that means machine LICM will hoist
  SQRT, DIV, etc. ARM will be somewhat aggressive with VFP and NEON
  instructions.
- Enable register pressure aware machine LICM by default.

cb18d38b76 Added a handful of x86-32 instructions that were missing so that llvm-mc would 
be more complete.  These are only expected to be used by llvm-mc with assembly
source so there is no pattern, [], in the .td files.  Most are being added to
X86InstrInfo.td as Chris suggested and only comments about register uses are
added.  Suggestions welcome on the .td changes as I'm not sure on every detail
of the x86 records.  More missing instructions will be coming.

fcc42f2f3a ARM instructions that are both predicated and set the condition codes 
have been printed with the "S" modifier after the predicate.  With ARM's
unified syntax, they are supposed to go in the other order.  We fixed this
for Thumb when we switched to unified syntax but missed changing it for
ARM.  Apparently we don't generate these instructions often because no one
noticed until now.  Thanks to Bill Wendling for the testcase!

2c335d364c Add support for vmov.f64/.f32 encoding. There's a bit of a hack going on 
here. The f32 in FCONSTS is handled as a double instead of a float in the
code. So the encoding of the immediate into the instruction isn't exactly in
line with the documentation in that regard. But given that we know it's handled
as a double, it doesn't cause any harm.
