3497782f38 Allow explicit physical registers for implicit operands.

7952d6088e 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.
This was part of the extensive changes to the way code generation occurs
for function call arguments and return values.
See log for CodeGen/PhyRegAlloc.cpp.

9635867d6f Several bug fixes: globals in call operands were not being pulled out; 
globals in some other places may not have been pulled out either;
globals in phi operands were being put just before the phi instead of
in the predecessor basic blocks.

d0d06ad4f3 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.

broken up into their elements.  Too many programs break because of this.

9b03633265 Because the format of the shift instructions is `shift r, shcnt, r', the 
instructions of format 3.12 and 3.13 cannot inherit from F3rdrs1, because that
implies that the two registers are the first two parameters to the instruction.

Thus I made the instructions inherit from F3rd again, and manually added an rs1
field AFTER the shcnt field in the instruction, which maps to the appropriate
place in the instruction.

The other changes are just elimination of unnecessary spaces.

9604416192 Makefile: Make SparcV9CodeEmitter.inc depend on SparcV9_F*.td as well. 
SparcV9_F3.td: F3_12 and F3_13 instructions have rd and rs1 fields. Also,
 their fields were totally screwed up. This seems to fix the problem.
