[PATCH] MIPS objdump: Add `eabi32` and `eabi64` ABI options

[Anghelo Carvajal]

From: angie <angheloalf95@gmail.com>

Extend gpr and fpr register names with names suitable for both EABIs.

Heavily inspired by the EABI documenation written by Eric Christopher,
which can be read at
https://sourceware.org/legacy-ml/binutils/2003-06/msg00436.html
