Un-revert: the buildbot failure in LLVM on lld-x86_64-win7 had me with
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.

We dump any non-empty assembler constant pools after a successful
parse of an assembly file that uses the ldr pseudo opcode. These

output with an AsmStreamer.
This patch changes the map data struture used to associate a section

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

Add support for positionally-encoded operands to FixedLenDecoderEmitter
Unfortunately, the PowerPC instruction definitions make heavy use of the
positional operand encoding heuristic to map operands onto bitfield variables
in the instruction definitions. Changing this to use name-based mapping is not
trivial, however, because additional infrastructure needs to be designed to
handle mapping of complex operands (with multiple suboperands) onto multiple
bitfield variables.
In the mean time, this adds support for positionally encoded operands to
FixedLenDecoderEmitter, so that we can generate a disassembler for the PowerPC
backend. To prevent an accidental reliance on this feature, and to prevent an
undesirable interaction with existing disassemblers, a backend must opt-in to
this support by setting the new decodePositionallyEncodedOperands
instruction-set bit to true.
When enabled, this iterates the variables that contribute to the instruction
encoding, just as the encoder does, and emulates the procedure the encoder uses
to map "numbered" operands to variables. The bit range for each variable is
also determined as the encoder determines them. This map is then consulted
during the decoder-generator's loop over operands to decode, allowing the
decoder to understand both position-based and name-based operand-to-variable
mappings.
As noted in the comment on the decodePositionallyEncodedOperands definition,
this support should be removed once it is no longer needed. There should be no
change to existing disassemblers.

llvm-cov: Added -f option for function summaries.
Similar to the file summaries, the function summaries output line,
branching and call statistics. The file summaries have been moved
outside the initial loop so that all of the function summaries can be
outputted before file summaries.
Also updated test cases.

Fix a problem with mips16 stubs when calls are transformed during
tail call optimization. Some more work may be needed for indirect
calls but this patch fixes the current regression in Prolangc++/trees.
S2 optimization as part of the general cleanup and optimization
of prolog and epilog was not saving S2 in this case and needed to.
