Note that support for rvalue references does not imply support
for the full set of move-related STL operations.

I've preserved support for an odd little thing in insert() where
we're trying to support inserting a new element from an existing
one.  If we actually want to support that, there's a lot more we
need to do:  insert can call either grow or push_back, neither of
which is safe against this particular use pattern.

Aliases for adding a negative immediate when using an explicit 'w'
suffix. E.g.,
        adds.w r2, #-16
        adds.w r2, r2, #-16
        addw r2, #-16
        addw r2, #-16
        addw r2, r2, #-16

Expressions for movw/movt don't always have an :upper16: or :lower16:
on them and that's ok. When they don't, it's just a plain [0-65536]
immediate result, effectively the same as a :lower16: variant kind.

This patch marks the X86 floating point stack registers ST0-ST7 as reserved
in order to avoid assertion failures in the register scavenger. The assertion
failures were “Bad machine code: Using an undefined physical register” and
“Bad machine code: MBB exits via unconditional fall-through but its successor
differs from its CFG successor!”.

Previously, an unsupported/unknown assembler directive issued a warning.
That's generally unsafe, and inconsistent with the behaviour of pretty
much every system assembler. Now that the MC assemblers are mature
enough to be the default on multiple targets, it's reasonable to
issue errors for these.

For target or platform directives that need to stay warnings, we
should add explicit handlers for them in, e.g., ELFAsmParser.cpp,
DarwinAsmParser.cpp, et. al., and issue the warning there.

The caller is already responsible for eating any additional input on the
line. Putting an additional EatToEndOfStatement() in ParseStatement()
causes an entire extra statement to be consumed when treating warnings
as errors. For example, test/MC/macros.s will assert() because the
.endmacro directive is missed as a result.

- Improved parameter names for clarity
- Added comments
- emitCommonSymbols should return void because its return value is not being
  used anywhere
- Attempt to reduce the usage of the RelocationValueRef type. Restricts it 
  for a single goal and may serve as a step for eventual removal.

The TargetPassManager's default constructor wants to initialize the PassManager
to 'null'. But it's illegal to bind a null reference to a null l-value. Make the
ivar a pointer instead.
