86ca8840a1 Need to insert all moves due to PHI nodes before *ALL* jumps in a predecessor 
basic block, as there could be multiple.

35a358d981 This should be more correct: invalidates physical registers that are used in 
an instruction to avoid using them to allocate to other virtual registers.

disappeared during the last checkin.

4ef74c8079 Start allocating stack space at [ebp-4] to not overwrite the return address. 
Also make all loads & stores 4-byte aligned for performance. ;)

260dbc79fc Take advantage of our knowledge of 2-address X86 instructions and 
register-allocated them appropriately.

dbb7b65bf3 Fun arithmetic with iterators aimed at fixing a bug: inserting instructions 
after the *current* instruction while keeping the iterator in the same
'logical' place.

a8ad93221a 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.

a1b4f0f85e Remove separate vector of implicit refs from MachineInstr, and 
instead record them as extra operands in the operands[] vector.
Also, move CallArgsDescriptor into this class instead of making it an
annotation on the machine instruction.
