25f31dcc8f add aliases for movs between seg registers and mem. There are multiple 
different forms of this instruction (movw/movl/movq) which we reported
as being ambiguous.  Since they all do the same thing, gas just picks the
one with the shortest encoding.  Follow its lead here.

This implements rdar://8208615

0d6d870628 go to great lengths to work around a GAS bug my previous patch 
exposed:

GAS doesn't accept "fcomip %st(1)", it requires "fcomip %st(1), %st(0)"
even though st(0) is implicit in all other fp stack instructions.

Fortunately, there is an alias for fcomip named "fcompi" and gas does
accept the default argument for the alias (boggle!).

As such, switch the canonical form of this instruction to "pi" instead
of "ip".  This makes the code generator and disassembler generate pi,
avoiding the gas bug.

bbd318b76a rework the rotate-by-1 instructions to be defined like the 
shift-by-1 instructions, where the asmstring doesn't contain
the implicit 1.  It turns out that a bunch of these rotate
instructions were completely broken because they used 1 
instead of $1.

This fixes assembly mismatches on "rclb	$1, %bl" and friends,
where we used to generate the 3 byte form, we now generate the
proper 2-byte form.

1beb2b3fc5 correct suffix matching to search for s/l/t suffixes on 
floating point stack instructions instead of looking for b/w/l/q.

This fixes issues where we'd accidentally match fistp to fistpl,
when it is in fact an ambiguous instruction.

This changes the behavior of llvm-mc to reject fstp, which was the
correct fix for rdar://8456389:
t.s:1:1: error: ambiguous instructions require an explicit suffix (could be 'fstps', 'fstpl', or 'fstpt')
fstp	(%rax)

it also causes us to correctly reject fistp and fist, which addresses
PR8528:

t.s:2:1: error: ambiguous instructions require an explicit suffix (could be 'fistps', or 'fistpl')
fistp (%rax)
^
t.s:3:1: error: ambiguous instructions require an explicit suffix (could be 'fists', or 'fistl')
fist (%rax)
^

Thanks to Ismail Donmez for tracking down the issue here!

98f9965c89 Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by element size. Instead, 
all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with
the immediate shifted left to reflect the increased element size.

34599f4aa8 The MC code couldn't handle ARM LDR instructions with negative offsets: 
vldr.64 d1, [r0, #-32]

The problem was with how the addressing mode 5 encodes the offsets. This change
makes sure that the way offsets are handled in addressing mode 5 is consistent
throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue"
method into an "Imm12" and "addressing mode 5" version. But not to worry! The
majority of the duplicated code has been unified.

1546322a9c Rename getAddrModeImm12OpValue to getAddrModeImmOpValue and expand it to work 
with immediates up to 16-bits in size. The same logic is applied to other LDR
encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in
VLDR's case). Removing the "12" allows it to be more generic.

81d051481e Implement enough of the missing instalias support to get 
aliases installed and working.  They now work when the
matched pattern and the result instruction have exactly
the same operand list.

This is now enough for us to define proper aliases for
movzx and movsx, implementing rdar://8017633 and PR7459.

Note that we do not accept instructions like:
  movzx 0(%rsp), %rsi

GAS accepts this instruction, but it doesn't make any
sense because we don't know the size of the memory
operand.  It could be 8/16/32 bits.

0d9ac34ffa Be more strict on when we produce an undefined reference. In gas a file with 
just

.type   foo,@object

will produce an undefined reference to foo. On the other hand, a file with
just

.weakref bar, foo

will not. It is somewhat hard to support both in MC since both statements
should create the symbols. It should be possible if we really need to by
adding to the flags, but hopefully that is not necessary.

With this patch we do not produce a undefined reference in any of those cases.
The assembly file needs an actual use for the undefined reference to be
present.

This is in preparation for a patch implementing .weakref.

309484bb46 When the "true" and "false" blocks of a diamond if-conversion are the same, 
do not double-count the duplicate instructions by counting once from the
beginning and again from the end.  Keep track of where the duplicates from
the beginning ended and don't go past that point when counting duplicates
at the end.  Radar 8589805.

This change causes one of the MC/ARM/simple-fp-encoding tests to produce
different (better!) code without the vmovne instruction being tested.
I changed the test to produce vmovne and vmoveq instructions but moving
between register files in the opposite direction.  That's not quite the same
but predicated versions of those instructions weren't being tested before,
so at least the test coverage is not any worse, just different.

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.

8a3030c6af Added a few tweaks to the Intel Descriptor-table support instructions to allow 
word forms and suffixed versions to match the darwin assembler in 32-bit and
64-bit modes.  This is again for use just with assembly source for llvm-mc .

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.
