This fixes some of the ridiculously complex code for optimizing the

PR15662: Optimized debug info produces out of order function parameters
When a function is inlined we lazily construct the variables
representing the function's parameters. After that, we add any remaining
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.
This fix causes us to always keep the arg variables at the start of the
variable list & in the original order from the source.

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.

should make the legact JIT work again (& adds test for that problem).
