[Orc] Add stack-realignment code to the i386 resolver function.
The resolver uses the fxsave/fxrstor instructions, which require 16-byte
alignment, to save SSE state to the stack. Since 16-byte alignment can't be
assumed on all OSes (and all i386 OSes share this function) - add code to
automatically bump the alignment to 16-bytes on entry to the function.
