With this patch we use the SectionIndex directly, instead of counting the

unused parameters.

If the function doesn't use all the parameters, or uses them out of
order, then the DWARF would produce them in that order, producing a
parameter order that doesn't match the source.

Tim Northover [Sat, 1 Jun 2013 09:55:14 +0000 (09:55 +0000)]
X86: change MOV64ri64i32 into MOV32ri64

The MOV64ri64i32 instruction required hacky MCInst lowering because it
was allocated as setting a GR64, but the eventual instruction ("movl")
only set a GR32. This converts it into a so-called "MOV32ri64" which
still accepts a (appropriate) 64-bit immediate but defines a GR32.
This is then converted to the full GR64 by a SUBREG_TO_REG operation,
thus keeping everyone happy.

This fixes a typo in the opcode field of the original patch, which
should make the legact JIT work again (& adds test for that problem).
