Split memcpy/memset/memmove intrinsics into i32/i64 versions, resolving

PR709, and paving the way for future progress.
Significantly refactor autoupgrading code, to handle the more complex case
(where we upgrade one argument in a function), and fix some bugs in it.
Testcase here: llvm/test/Regression/Bytecode/memcpy.ll

- Fixed some priority calculation bugs that were causing bug 478. Among them:
...
a predecessor appearing more than once in the operand list was counted as
multiple predecessor; priority1 should be updated during scheduling;
CycleBound was updated after the node is inserted into priority queue; one
of the tie breaking condition was flipped.
- Take into consideration of two address opcodes. If a predecessor is a def&use
operand, it should have a higher priority.
- Scheduler should also favor floaters, i.e. nodes that do not have real
predecessors such as MOV32ri.
- The scheduling fixes / tweaks fixed bug 478:
.text
.align 4
.globl _f
_f:
movl 4(%esp), %eax
movl 8(%esp), %ecx
movl %eax, %edx
imull %ecx, %edx
imull %eax, %eax
imull %ecx, %ecx
addl %eax, %ecx
leal (%ecx,%edx,2), %eax
ret
It is also a slight performance win (1% - 3%) for most tests.

void foo(float a, int *b) { *b = a; }

stfd f0, -8(r1)
lwz r2, -4(r1)
