[PATCH] D52125: X86, AArch64, ARM: Do not attach debug location to spill/reload instructions

Spill/reload instructions are artificially generated by the compiler and
have no relation to the original source code. So the best thing to do is
not attach any debug location to them (instead of just taking the next
debug location we find on following instructions).
