this commit as the only one on the Blamelist so I quickly reverted this.
However it was actually Nick's change who has since fixed that issue.

Original commit message:

Changed the X86 assembler for intel syntax to work with directional labels.

The X86 assembler as a separate code to parser the intel assembly syntax
in X86AsmParser::ParseIntelOperand().  This did not parse directional labels.
And if something like 1f was used as a branch target it would get an
"Unexpected token" error.

The fix starts in X86AsmParser::ParseIntelExpression() in the case for
AsmToken::Integer, it needs to grab the IntVal from the current token
then look for a 'b' or 'f' following an Integer.  Then it basically needs to
do what is done in AsmParser::parsePrimaryExpr() for directional
labels.  It saves the MCExpr it creates in the IntelExprStateMachine
in the Sym field.

When it returns to X86AsmParser::ParseIntelOperand() it looks
for a non-zero Sym field in the IntelExprStateMachine and if
set it creates a memory operand not an immediate operand
it would normally do for the Integer.

Ensure deterministic when printing ARM assembler constant pools

We dump any non-empty assembler constant pools after a successful
parse of an assembly file that uses the ldr pseudo opcode. These
per-section constant pools should be output in a deterministic order
to ensure that we always generate the same output when printing the
output with an AsmStreamer.

This patch changes the map data struture used to associate a section
with its constant pool to a MapVector to ensure deterministic
output. Because this map type does not support deletion, we now
check that the constant pool is not empty before dumping its entries
and clear the entries after emitting them with the streamer.

Changed the X86 assembler for intel syntax to work with directional labels.

The X86 assembler has a separate code to parser the intel assembly syntax
in X86AsmParser::ParseIntelOperand().  This did not parse directional labels.
And if something like 1f was used as a branch target it would get an
"Unexpected token" error.

The fix starts in X86AsmParser::ParseIntelExpression() in the case for
AsmToken::Integer, it needs to grab the IntVal from the current token
then look for a 'b' or 'f' following the Integer.  Then it basically needs to
do what is done in AsmParser::parsePrimaryExpr() for directional
labels.  It saves the MCExpr it creates in the IntelExprStateMachine
in the Sym field.

When it returns to X86AsmParser::ParseIntelOperand() it looks
for a non-zero Sym field in the IntelExprStateMachine and if
set it creates a memory operand not an immediate operand
it would normally do for the Integer.

Implement the ldr-pseudo opcode for ARM assembly

The ldr-pseudo opcode is a convenience for loading 32-bit constants.
It is converted into a pc-relative load from a constant pool. For
example,

  ldr r0, =0x10001
  ldr r1, =bar

will generate this output in the final assembly

  ldr r0, .Ltmp0
  ldr r1, .Ltmp1
  ...
  .Ltmp0: .long 0x10001
  .Ltmp1: .long bar

Sketch of the LDR pseudo implementation:
  Keep a map from Section => ConstantPool

  When parsing ldr r0, =val
    parse val as an MCExpr
    get ConstantPool for current Section
    Label = CreateTempSymbol()
    remember val in ConstantPool at next free slot
    add operand to ldr that is MCSymbolRef of Label

  On finishParse() callback
    Write out all non-empty constant pools
    for each Entry in ConstantPool
      Emit Entry.Label
      Emit Entry.Value

Possible improvements to be added in a later patch:
  1. Does not convert load of small constants to mov
     (e.g. ldr r0, =0x1 => mov r0, 0x1)
  2. Does reuse constant pool entries for same constant
