This makes MCAsmInfo::getExprForFDESymbol() a virtual function and overrides it in SparcMCAsmInfo.

Otherwise, assembler (gas) fails to assemble them with error message "operation
combines symbols in different segments". This is because MC computes
pc_rel entries with subtract expression between labels from different sections.

[SparcV9] Use correct register class (I64RegClass) to hold the address of  _GLOBAL_OFFSET_TABLE_ in sparcv9.

With this the target streamers will be able to know the target features that
are in use.

The popc instruction is defined in the SPARCv9 instruction set
architecture, but it was emulated on CPUs older than Niagara 2.

This has a few advantages:
* Only targets that use a MCTargetStreamer have to worry about it.
* There is never a MCTargetStreamer without a MCStreamer, so we can use a
  reference.
* A MCTargetStreamer can talk to the MCStreamer in its constructor.

Sweep the codebase for common typos. Includes some changes to visible function
names that were misspelt.

Add test cases to check parsing of v9 double registers and their aliased quad registers.

code this looks correct, but could use review. The previous

promotion code, Tablegen will now select FPExt for floating point promotions
(previously it had returned AExt, which is not valid for floating point types).

Any out-of-tree targets that were relying on AExt being returned for FP
promotions will need to update their code check for FPExt instead.

This will allow it to be called from target independent parts of the main
streamer that don't know if there is a registered target streamer or not. This
in turn will allow targets to perform extra actions at specified points in the
interface: add extra flags for some labels, extra work during finalization, etc.

Targets like SPARC and MIPS have delay slots and normally bundle the
delay slot instruction with the corresponding terminator.

Teach isBlockOnlyReachableByFallthrough to find any MBB operands on
bundled terminators so SPARC doesn't need to specialize this function.

This is different from the argument passing convention which puts the
first float argument in %f1.

With this patch, all returned floats are treated as if the 'inreg' flag
were set. This means multiple float return values get packed in %f0,
%f1, %f2, ...

Note that when returning a struct in registers, clang will set the
'inreg' flag on the return value, so that behavior is unchanged. This
also happens when returning a float _Complex.

[Sparc] Bundle instruction with delay slow and its filler. Now, we can use -verify-machineinstrs with SPARC backend.

[Sparc] Emit retl/ret instead of jmp instruction. It improves the readability of the assembly generated.

subsequent changes are easier to review. About to fix some layering
issues, and wanted to separate out the necessary churn.

Also comment and sink the include of "Windows.h" in three .inc files to
match the usage in Memory.inc.
