This is a bulk commit that implements the following primary improvements:
...
* We can now fold cast instructions into select instructions that
have at least one constant operand.
* We now optimize expressions more aggressively based on bits that are
known to be zero. These optimizations occur a lot in code that uses
bitfields even in simple ways.
* We now turn more cast-cast sequences into AND instructions. Before we
would only do this if it if all types were unsigned. Now only the
middle type needs to be unsigned (guaranteeing a zero extend).
* We transform sign extensions into zero extensions in several cases.
This corresponds to these test/Regression/Transforms/InstCombine testcases:
2004-11-22-Missed-and-fold.ll
and.ll: test28-29
cast.ll: test21-24
and-or-and.ll
cast-cast-to-and.ll

Fix a FIXME: Select instructions on longs were miscompiled.
...
While we're at it, improve codegen of select instructions. For this
testcase:
int %test(bool %C, int %A, int %B) {
%D = select bool %C, int %A, int %B
ret int %D
}
We used to generate this code:
_test:
cmpwi cr0, r3, 0
bne .LBB_test_2 ;
.LBB_test_1: ;
b .LBB_test_3 ;
.LBB_test_2: ;
or r5, r4, r4
.LBB_test_3: ;
or r3, r5, r5
blr
Now we emit:
_test:
cmpwi cr0, r3, 0
bne .LBB_test_2 ;
.LBB_test_1: ;
or r4, r5, r5
.LBB_test_2: ;
or r3, r4, r4
blr

Substantially improve the code generated by non-folded setcc instructions.
...
In particular, instead of compiling this:
bool %test(int %A, int %B) {
%C = setlt int %A, %B
ret bool %C
}
to this:
test:
save %sp, -96, %sp
subcc %i0, %i1, %g0
bl .LBBtest_1 !
nop
ba .LBBtest_2 !
nop
.LBBtest_1: !
or %g0, 1, %i0
ba .LBBtest_3 !
nop
.LBBtest_2: !
or %g0, 0, %i0
ba .LBBtest_3 !
nop
.LBBtest_3: !
restore %g0, %g0, %g0
retl
nop
We now compile it to this:
test:
save %sp, -96, %sp
subcc %i0, %i1, %g0
or %g0, 1, %i0
bl .LBBtest_2 !
nop
.LBBtest_1: !
or %g0, %g0, %i0
.LBBtest_2: !
restore %g0, %g0, %g0
retl
