The local register allocator has to spill dirty callee saved registers before a
...
call that might throw. The landing pad assumes that all registers are in stack
slots.
We used to spill those dirty CSRs after the call, and the stack slots would be
wrong when arriving at the landing pad.

Reject really weird coalescer case when trying to merge identical subregisters
...
of different register classes. e.g.
%reg1048:3<def> = EXTRACT_SUBREG %RAX<kill>, 3
Where %reg1048 is a GR32 register. This is not impossible to handle, but it is
pretty hard and very rare.
This should unbreak the dragonegg builder.
