[mips] Promote all integral/enumeration types to the GPR width

Summary:
Ensure all integral/enumeration types are appropriately annotated with
signext/zeroext. In particular, i32 now has these attributes when using the
N32/N64 ABI. This paves the way for accurately representing the way the
N32/N64 ABI's promotes integer arguments to i64.

[mips] Mark aggregate arguments passed in registers with the inreg attribute

Summary:
This allows us to easily identify them in the backend which in turn allows us
to handle them correctly for big-endian targets (where they must be shifted
into the upper bits of the register).

Add frontend support for __vectorcall

Wire it through everywhere we have support for fastcall, essentially.

This allows us to parse the MSVC "14" CTP headers, but we will
miscompile them because LLVM doesn't support __vectorcall yet.

CodeGen: correct materialize temporary aggregates in ARC mode

Avoid an assertion when materializing a lifetime type aggregate temporary.  When
performing CodeGen for ObjC++, we could generate a lifetime-only aggregate
temporary by using an initializer list (which is effectively an array).  We
would reach through the temporary expression, fishing out the inner expression.
If this expression was a lifetime expression, we would attempt to emit this as a
scalar.  This would eventually result in an assertion as the emission would
eventually assert that the expression being emitted has a scalar evaluation
kind.

Add a case to handle the aggregate expressions.  Use the EmitAggExpr to emit the
aggregate expression rather than the EmitScalarInit.

Addresses PR21347.

Lex: Fix an invalid access into a SmallString

We would crash because we used operator[] to access past the end of a
SmallString.  This occured because our token had length zero.

Instead, form the pointer using .data() and arithmetic.  This is safe
because this forms a one-past-the-end pointer and it is only used to
compare with another one-past-the-end pointer.
