The X86FixupLEAs pass for Intel Atom must not call convertToThreeAddress
on ADD16rr opcodes, if src1 != src, since that would cause
convertToThreeAddress to try to create a virtual register. This is not
permitted after register allocation, which is when the X86FixupLEAs pass
runs.

This patch fixes PR16785.
