MIPS: Fix several failures due to unsupported Sed and Seh innstructions on MIPS32R1

MIPS: Simulate SEB and SEH instructions on MIPS32R1 through MacroAssembler

SEB and SEH instructions are not available on MIPS32R1. This caused several failures on
MIPS32R1 in mjsunit/wasm/* and mjsunit/asm test suites.
This fix simulates these instruction in MacroAssembler for those architectures that do not support them.

LGTM, just fix SED and SED in description to SEH and SED.

Actually should be SEH and SEB, should be fixed in two places.
