5e265b29ea fastcc functions that return double values now return them in xmm0 on x86-32. 
This implements CodeGen/X86/fp-stack-ret.ll:test[23]

2a9bdd74f2 move LowerRET into the 'Return Value Calling Convention Implementation' 
section of the file.

339b439d47 make all Lower*CallTo implementations use LowerCallResult to handle their 
result value stuff.  This eliminates a bunch of duplicated code and now
GetRetValueLocs is the sole place that decides where a value is returned.

3085e15117 factor a bunch of code out of LowerCCCCallTo into a new LowerCallResult 
function.  This function now uses GetRetValueLocs to determine *where*
the result values are located and concerns itself with *how* to pull the
values out.

cb18656734 simplify result value lowering by splitting the selection of *where* to return 
registers out from the logic of *how* to return them.

This changes X86-64 to mark EAX live out when returning a 32-bit value,
where before it marked RAX liveout.

f734ea21a3 Implement support for non-standard integer bit widths of any size. The 
rules alignment is to pick the alignment that corresponds to the smallest
specified alignment that is larger than the bit width of the type or the
largest specified integer alignment if none are larger than the bitwidth
of the type. For the byte size, the size returned is the next larger
multiple of the alignment for that type (using the above rule). This patch
also changes bit widths from "short" to "uint32_t" to ensure there are
enough bits to specify any bit width that LLVM can handle (currently 2^23);
16-bits isn't enough.
