[mips] Fix unaligned access in Low Level Interpreter (LLINT).

2014-09-05T14:23:06+00:00

Address loads used with btbxx opcodes were wrongly converted to lw instruction
instead of lbu, leading to unaligned access on mips platforms.

[sh4] Introduce const pools in LLINT.

2013-10-18T09:36:22+00:00

https://bugs.webkit.org/show_bug.cgi?id=122746

Reviewed by Michael Saboff.

In current implementation of LLINT for sh4, immediate values outside range -128..127 are
loaded this way:

    mov.l .label, rx
    bra out
    nop
    .balign 4
    .label: .long immvalue
    out:

This change introduces const pools for sh4 implementation to avoid lots of useless branches
and reduce code size. It also removes lines of dirty code, like jmpf and callf.

* offlineasm/instructions.rb: Remove jmpf and callf sh4 specific instructions.
