MIPS: Remove GCC_IMM_ASM & GCC_REG_ACCUM macros
asm/compiler.h defined GCC_IMM_ASM & GCC_REG_ACCUM macros, both of which
are defined differently for GCC pre-3.4 or GCC 3.4 & higher. We only
support building with GCC 4.6 & higher since commit cafa0010cd51 ("Raise
the minimum required gcc version to 4.6"), which makes the pre-3.4
definition dead code.
Rather than leave the macro definitions around, inline the GCC 3.4 &
higher definitions into the single file that uses them & remove the
macros entirely.
