18bfb1399a Added functions to generate prolog and epilog code.
Use JMPLRET instead of RETURN for method returns so that

0ba9c3d61b 1. Move most of the constant-fixup code into machine-independent file
InstrSelectionSupport.cpp.  It now happens in a bottom-up pass on
   each BURG tree after the original top-down selection pass on the tree.
2. Handle global values as constants (viz., constant addresses).

2f08c4c828 Insert code to load constants used as Call or Return arguments.
Also, note return value of a Call as an "implicitUse".

4bdadf3b6f Several fixes:
(1) Avoid hard-coding some register numbers.
(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".
