Do not hastily change the Opcode from 'r' to 'i' type if we're not actually
...
SETTING the operand to be an immediate or have verified that one of the operands
is really a SignExtended or Unextended immediate value already, which warrants
an 'i' opcode.

I have finally seen the light. The code to change the opcode must live higher in
...
the loop, and in both cases. In the first case, it is a VReg that is a constant
so it may be actually converted to a constant. In the second case, it is already
a constant, but then if it doesn't change its type (e.g. to become a register
and have the value loaded from memory if it is too large to live in its
instruction field), we must change the opcode BEFORE the 'continue', otherwise
we miss the opportunity.

Changes to allow explicit physical register arguments that have been

preallocated. While reg-to-reg dependences were already handled, this
change required new code for adding edges to/from call instructions.

for function call arguments and return values.

Extensive changes to the way code generation occurs for function
...
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

This should fix the bug seen with some registers not being allocated
...
correctly: skipping instructions by incorrectly incrementing the pointer.
Also adds support for building a reg-to-regclass map, and splits the function
for saving register to stack into two, one suitable for virtual registers
(which also assigns it a physical register) and one for simply storing back
physical registers.
