Implement a couple of more simplifications. This lets us codegen:
...
int test2(int * P, int* Q, int A, int B) {
return P+A == P;
}
into:
test2:
movl 4(%esp), %eax
movl 12(%esp), %eax
shll $2, %eax
cmpl $0, %eax
sete %al
movzbl %al, %eax
ret
instead of:
test2:
movl 4(%esp), %eax
movl 12(%esp), %ecx
leal (%eax,%ecx,4), %ecx
cmpl %eax, %ecx
sete %al
movzbl %al, %eax
ret
ICC is producing worse code:
test2:
movl 4(%esp), %eax #8.5
movl 12(%esp), %edx #8.5
lea (%edx,%edx), %ecx #9.9
addl %ecx, %ecx #9.9
addl %eax, %ecx #9.9
cmpl %eax, %ecx #9.16
movl $0, %eax #9.16
sete %al #9.16
ret #9.16
as is GCC (looks like our old code):
test2:
movl 4(%esp), %edx
movl 12(%esp), %eax
leal (%edx,%eax,4), %ecx
cmpl %edx, %ecx
sete %al

Make the 2-address instruction lowering pass smarter in two ways:
...
1. If we are two-addressing a commutable instruction and the LHS is not the
last use of the variable, see if the instruction is the last use of the
RHS. If so, commute the instruction, allowing us to avoid a
register-register copy in many cases for common instructions like ADD, OR,
AND, etc on X86.
2. If #1 doesn't hold, and if this is an instruction that also existing in
3-address form, promote the instruction to a 3-address instruction to
avoid the register-register copy. We can do this for several common
instructions in X86, including ADDrr, INC, DEC, etc.
This patch implements test/Regression/CodeGen/X86/commute-two-addr.ll,
overlap-add.ll, and overlap-shift.ll when I check in the X86 support for it.

* Improve comments/documentation substantially
...
* Eliminate the releaseMemory method, this is not an analysis
* Change the fixed, active, and inactive lists of intervals to maintain an
iterator for the current position in the interval. This allows us to do
constant time increments of the iterator instead of having to do a binary
search to find our liverange in our liveinterval all of the time, which
substantially speeds up cases where LiveIntervals have many LiveRanges
- which is very common for physical registers. On targets with many
physregs, this can make a noticable difference.
With a release build of LLC for PPC, this halves the time in
processInactiveIntervals and processActiveIntervals, from 1.5s to .75s.
This also lays the ground for more to come.

useful when you have a reference like:
int A[100];
void foo() { A[10] = 1; }
In this case, &A[10] is a single constant and should be treated as such.

other operand type is.

This patch fixes the nasty bug that caused 175.vpr to fail for X86 last night.
...
The problem occurred when trying to reload this instruction:
MOV32mr %reg2326, 8, %reg2297, 4, %reg2295
The value of reg2326 was available in EBX, so it was reused from there, instead
of reloading it into EDX.
The value of reg2297 was available in EDX, so it was reused from there, instead
of reloading it into EDI.
The value of reg2295 was not available, so we tried reloading it into EBX, its
assigned register. However, we checked and saw that we already reloaded
something into EBX, so we chose what reg2326 was assigned to (EDX) and reloaded
into that register instead.
Unfortunately EDX had already been used by reg2297, so reloading into EDX
clobbered the value used by the reg2326 operand, breaking the program.
The fix for this is to check that the newly picked register is ok. In this
case we now find that EDX is already used and try using EDI, which succeeds.

When a virtual register is folded into an instruction, keep track of whether
...
it was a use, def, or both. This allows us to be less pessimistic in our
analysis of them. In practice, this doesn't make a big difference, but it
doesn't hurt either.

Add a simple little improvement to the local spiller to keep track of stores
...
and delete them if they turn out to be dead. This is a useful little hack
that even speeds up some programs. For example, it speeds up Ptrdist/ks
from 17.53s to 15.59s, and 188.ammp from 149s to 146s.
This also speeds up llc :)

Substantially revamp the local spiller, causing it to actually improve the
...
generated code over the simple spiller. The new local spiller generates
substantially better code than the simple one in some cases, by reusing
values that are loaded out of stack slots and kept available in registers.
This primarily helps programs that are spilling a lot, and there is still
stuff that can be done to improve it. This patch makes the local spiller
the default, as it's only a tiny bit slower than the simple spiller (it
increases the runtime of llc by < 1%).
Here are some numbers with speedups.

Switch from defaulting to the 'local' spiller to the 'simple' spiller. The
...
two spillers produce perfectly identical code (at least on povray and eon),
but the simple spiller is substantially faster than the local spiller. Once
the local spiller is improved, we can switch back.
Switching cuts 5.2% off of the llc time for povray (about 1.3s).
