3d6e4c3111 X86: Fix misencode of RI64mi8. This fixes OpenSSL / x86_64-apple-darwin10 / clang -O3. 
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112089 91177308-0d34-0410-b5e6-96231b3b80d8

77e2dd7bb2 X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same 
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

90b374cded MC/X86: We now match instructions like "incl %eax" correctly for the arch we are 
assembling; remove crufty custom cleanup code.

1cf44fc051 fix rdar://7873482 by teaching the instruction encoder to emit 
segment prefixes.  Daniel wrote most of this patch.

04ac770be9 The BT64ri8 record in X86Instr64bit.td was missing a REX_W which is required 
for the 64-bit version of the Bit Test instruction.

b5505d0ee3 reapply r103668 with a fix. Never make "minor syntax changes" 
after testing before committing.

0de8e3f10a moffset forms of moves are x86-32 only, make the parser 
lower them to the correct x86-64 instructions since we 
don't have a clean way to handle this in td files yet.

were missing it on some movq instructions and were not including the appropriate
PCrel bias.

0f53cf2236 add a special relocation type for movq loads for object 
files that produce special relocation types where the 
linker changes movq's into lea's.

f068304b1f rip out the 'heinous' x86 MCCodeEmitter implementation. 
We still have the templated X86 JIT emitter, *and* the
almost-copy in X86InstrInfo for getting instruction sizes.
