SVN rev 210096 on 2010-07-15 01:47:47Z by imp
Remove one layer of indirection. No need to call cpu_throw which then
calls mips_cpu_call via an obfuscated assembler call. Instead, delete
the current cpu_throw, and rename mips_cpu_throw to cpu_throw. This
is nicer to the cache on each context switch (since fixed jumps can be
prefected, while jumps through a register can't). Incidentally, it
also saves about 5 or 6 instructions.
