4d43d0fd99 move FlattenVariants out of AsmMatcherEmitter into a shared
CodeGenInstruction::FlattenAsmStringVariants method.  Use it
to simplify the code in AsmWriterInst, which now no longer 
needs to worry about variants.

52de0ef922 add a FIXME, $lane in ARM is an issue that needs to be resolved before
this can start rejecting instructions.

4d1189f385 reject instructions that contain a \n in their asmstring. Mark
various X86 and ARM instructions that are bitten by this as isCodeGenOnly,
as they are.

d6d9dd9f5e fix a crash on:
let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 {

we now get:

let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 {

150d20e8fc fix the !eq operator in tblgen to return a bit instead of an int.
Use this to make the X86 and ARM targets set isCodeGenOnly=1 
automatically for their instructions that have Format=Pseudo,
resolving a hack in tblgen.

a4a3a5e3c2 two changes: make the asmmatcher generator ignore ARM pseudos properly,
and make it a hard error for instructions to not have an asm string.
These instructions should be marked isCodeGenOnly.

efa53760fe the asm matcher can't handle operands with modifiers (like ${foo:bar}).
Instead of silently ignoring these instructions, emit a hard error and
force the target author to either refactor the target or mark the 
instruction 'isCodeGenOnly'.

Mark a few instructions in ARM and MBlaze as isCodeGenOnly the are 
doing this.
