Fix BU datastructures with povray!
...
The problem was that we were merging a field of a node with a value that was
deleted. Thanks to bugpoint for reducing povray to a nice small 3 function
example. :)

Minor changes, remove some debugging code that got checked in somehow.
...
Make sure to scope the NodeMap passed into cloneInto so that it doesn't point
to nodes that are deleted. Add some FIXME's for future performance enhancements.

TargetCacheInfo has been removed; its only uses were to propagate a constant

(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

Handle passing constant integers to functions much more efficiently. Instead
...
of generating this code:
mov %EAX, 4
mov DWORD PTR [%ESP], %EAX
mov %AX, 123
movsx %EAX, %AX
mov DWORD PTR [%ESP + 4], %EAX
call Y
we now generate:
mov DWORD PTR [%ESP], 4
mov DWORD PTR [%ESP + 4], 123
call Y
Which hurts the eyes less. :)
Considering that register pressure around call sites is already high (with all
of the callee clobber registers n stuff), this may help a lot.

Fix a minor code-quality issue. When passing 8 and 16-bit integer constants
...
to function calls, we would emit dead code, like this:
int Y(int, short, double);
int X() {
Y(4, 123, 4);
}
--- Old
X:
sub %ESP, 20
mov %EAX, 4
mov DWORD PTR [%ESP], %EAX
*** mov %AX, 123
mov %AX, 123
movsx %EAX, %AX
mov DWORD PTR [%ESP + 4], %EAX
fld QWORD PTR [.CPIX_0]
fstp QWORD PTR [%ESP + 8]
call Y
mov %EAX, 0
# IMPLICIT_USE %EAX %ESP
add %ESP, 20
ret
Now we emit:
X:
sub %ESP, 20
mov %EAX, 4
mov DWORD PTR [%ESP], %EAX
mov %AX, 123
movsx %EAX, %AX
mov DWORD PTR [%ESP + 4], %EAX
fld QWORD PTR [.CPIX_0]
fstp QWORD PTR [%ESP + 8]
call Y
mov %EAX, 0
# IMPLICIT_USE %EAX %ESP
add %ESP, 20
ret
Next up, eliminate the mov AX and movsx entirely!
