Chris Lattner b80ab36179 Give AsmMatcherInfo a CodeGenTarget, which simplifies a bunch of 
argument passing.  Consolidate all SingletonRegister detection
and handling into a new 
InstructionInfo::getSingletonRegisterForToken method instead of
having it scattered about.  No change in generated .inc files.

John McCall e6e622e789 Only apply -fvisibility-inlines-hidden to definitions. Apparently 
isInlined() just gives meaningless results for non-definitions.

Fixes rdar://problem/8614470

Chris Lattner 25d9c7fa2e 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.

Chris Lattner 40dd3f0939 add a FIXME, $lane in ARM is an issue that needs to be resolved before 
this can start rejecting instructions.

Chris Lattner 941c19b7ba 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.

Anders Carlsson 0a14ee9ed8 Get rid of more calls to getBaseClassOffsetInBits.

Anders Carlsson 3f01871647 Port over a couple of getVBaseClassOffsetInBits call sites to use getVBaseClassOffset instead.

Anders Carlsson fd88a6160d Rename getBaseClassOffset to getBaseClassOffsetInBits and introduce a getBaseClassOffset which returns the offset in CharUnits. Do the same thing for getVBaseClassOffset.

Chandler Carruth baa5126dbc Add a specialization for 'long', a hole in the set of fundamental 
specializations provided here. This is a little annoying because its size
changes from platform to platform. If possible, I may follow up with a patch
that uses standard constants to simplify much of this, but assuming for now
that was avoided for a reason.

Bill Wendling 0392f1b437 Disable the peephole optimizer until 186.crafty on armv6 is fixed. This is what 
looks like is happening:

Without the peephole optimizer:
  (1)   sub     r6, r6, #32
        orr     r12, r12, lr, lsl r9
        orr     r2, r2, r3, lsl r10
  (x)   cmp     r6, #0
        ldr     r9, LCPI2_10
        ldr     r10, LCPI2_11
  (2)   sub     r8, r8, #32
  (a)   movge   r12, lr, lsr r6
  (y)   cmp     r8, #0
LPC2_10:
        ldr     lr, [pc, r10]
  (b)   movge   r2, r3, lsr r8

With the peephole optimizer:
        ldr     r9, LCPI2_10
        ldr     r10, LCPI2_11
  (1*)  subs    r6, r6, #32
  (2*)  subs    r8, r8, #32
  (a*)  movge   r12, lr, lsr r6
  (b*)  movge   r2, r3, lsr r8

(1) is used by (x) for the conditional move at (a). (2) is used by (y) for the
conditional move at (b). After the peephole optimizer, these the flags resulting
from (1*) are ignored and only the flags from (2*) are considered for both
conditional moves.

Chris Lattner d689026899 fix a crash on:

Chris Lattner 7ff334687d 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.

Chris Lattner 9492c17baf two changes: make the asmmatcher generator ignore ARM pseudos properly,

These instructions should be marked isCodeGenOnly.

Chris Lattner 9293008e90 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.

Duncan Sands fa7e6f2417 Remove CCAssignFnForRet from X86 FastISel in favour of RetCC_X86,
