Vladimir Stefanovic 3daf8bc96a [mips] Emit .reloc R_{MICRO}MIPS_JALR along with j(al)r(c) $25
The callee address is added as an optional operand (MCSymbol) in
AdjustInstrPostInstrSelection() and then used by asm printer to insert:
'.reloc tmplabel, R_MIPS_JALR, symbol
tmplabel:'.
Controlled with '-mips-jalr-reloc', default is true.

Stefan Maksimovic 4a612d4bf2 [mips] Sign extend i32 return values on MIPS64
Override getTypeForExtReturn so that functions returning
an i32 typed value have it sign extended on MIPS64.

Also provide patterns to get rid of unneeded sign extensions
for arithmetic instructions which implicitly sign extend
their results.
