[LLVMdev] Best way to interface with MSVC _ftol2 runtime function for fptoui?

[Joe Groff]

Here is a patch that integrates the WIN_FTOL pseudo-insn a bit better
with the floating-point register allocator by following a simplified
version of what InlineAsm does, as you suggested. Does this look
closer to being right? Thanks again for all your help.
