Made csa and csb work with mcg; adjust the libem functions and the
...
corresponding invocation in the ncg table so the same helpers can be used for
both mcg and ncg. Add a new IR opcode, FARJUMP, which jumps to a helper
function but saves volatile registers.

A bb's regsin are no longer the same as those of its first instruction;
...
occasionally the first hop of a block would try to rearrange its registers (due
to evicted throughs), resulting in the phi moves copying values into the wrong
registers.

Reenable eviction of corrupted registers, which had been broken by a previous

Update the table to return call output values in the right registers. Fix the

register allocator so the corrupted registers only apply to throughs
(otherwise, you can't put output registers in corrupted registers).

Rework the way stack frames are laid out to be simpler and, hopefully, more

Lots more opcodes. Rearrange the stack layout so that fp->ab is a fixed value

Don't generate phis if unnecessary (because this breaks the

Swaps work (at least for registers). More opcodes. Rearrange the stack layout

Remove the bytes1, bytes2, bytes4, bytes8 attributes; remove the concept of a

register 'type'; now use int/float/long/double throughout to identify
