rearchitect the registration mechanism used by the command line option stuff.
...
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called. In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main. Most of that
memory is now allocated by non-commandline related stuff.

mov r2, #0

equality comparisons of a constant. This allows us to codegen the 'sintzero'
loop in PR1288 as:
LBB1_1: ;cond_next
li r4, 0
addi r2, r2, 1
stw r4, 0(r3)
addi r3, r3, 4
cmpwi cr0, r2, -1
bne cr0, LBB1_1 ;cond_next
instead of:
LBB1_1: ;cond_next
addi r2, r2, 1
li r4, 0
xoris r5, r2, 65535
stw r4, 0(r3)
addi r3, r3, 4
cmplwi cr0, r5, 65535
bne cr0, LBB1_1 ;cond_next
This implements CodeGen/PowerPC/compare-simm.ll, and also cuts 74
instructions out of kc++.

Various passes before isel split edges and do other CFG-restructuring changes.
...
isel has its own particular features that it wants in the CFG, in order to
reduce the number of times a constant is computed, etc. Make sure that we
clean up the CFG before doing any other things for isel. Doing so can
dramatically reduce the number of split edges and reduce the number of
places that constants get computed. For example, this shrinks
CodeGen/Generic/phi-immediate-factoring.ll from 44 to 37 instructions on X86,
and from 21 to 17 MBB's in the output. This is primarily a code size win,
not a performance win.
This implements CodeGen/Generic/phi-immediate-factoring.ll and PR1296.

1. Clear up confusion between "GotBits" and "ExpectBits". GotBits is the
type actually provided. ExpectedBits is the type expected for the

suffix expected and making sure the suffix matches the function name. It
also includes some intrinsic-specific checks such as ensuring that the
bswap parameter and result are the same width and an even number of bytes.

Add support for the v1i64 type. This makes better code for this:
...
#include <mmintrin.h>
extern __m64 C;
void baz(__v2si *A, __v2si *B)
{
*A = C;
_mm_empty();
}
We get this:
_baz:
call "L1$pb"
"L1$pb":
popl %eax
movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
movq (%eax), %mm0
movl 4(%esp), %eax
movq %mm0, (%eax)
emms
ret
GCC gives us this:
_baz:
pushl %ebx
call L3
"L00000000001$pb":
L3:
popl %ebx
subl $8, %esp
movl L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
movl (%eax), %edx

Remove a use of getLowBitsSet that caused the mask used for replacement of
shl/lshr pairs with an AND instruction to be computed incorrectly. Its not
clear exactly why this is the case. This solves the disappearing shifts
problem, but it doesn't fix Regression/C/2003-05-21-UnionBitFields. It
seems there is more going on.

More APIntification:
...
* Convert the last use of a uint64_t that should have been an APInt.
* Change ComputeMaskedBits to have a const reference argument for the Mask
so that recursions don't cause unneeded temporaries. This causes temps
to be needed in other places (where the mask has to change) but this
change optimizes for the recursion which is more frequent.
* Remove two instances of &ing a Mask with getAllOnesValue. Its not
needed any more because APInt is accurate in its bit computations.
* Start using the getLowBitsSet and getHighBits set methods on APInt
instead of shifting. This makes it more clear in the code what is
going on.

For PR1248:
...
* Fix some indentation and comments in InsertRangeTest
* Add an "IsSigned" parameter to AddWithOverflow and make it handle signed
additions. Also, APIntify this function so it works with any bitwidth.
* For the icmp pred ([us]div %X, C1), C2 transforms, exit early if the
div instruction's RHS is zero.
* Finally, for icmp pred (sdiv %X, C1), -C2, fix an off-by-one error. The
HiBound needs to be incremented in order to get the range test correct.
