41aaf7016e Fix bug 537 test 2, which checks to make sure that we fold A+(B-A) -> B for
integer types.  Add a couple checks to not perform these kinds of transform
on floating point values.

244e92eaab When compiled with GCC 4.0, a latent bug was exposed where both SparcV9
and the target independant register allocator were both using a class named
'LiveRange'.  This lead to the target independant code calling code in the
SparcV9 backend, which crashed.  Fixed by renaming SparcV9's LiveRange to
V9LiveRange.

b2c4bf3ff6 Handle some more real world cases of rlwimi. These don't come up that
regularly in "normal" code, but for things like software graphics, they
make a big difference.

For the following code:
unsigned short Trans16Bit(unsigned srcA,unsigned srcB,unsigned alpha)
{
	unsigned tmpA,tmpB,mixed;
	tmpA = ((srcA & 0x03E0) << 15) | (srcA & 0x7C1F);
	tmpB = ((srcB & 0x03E0) << 15) | (srcB & 0x7C1F);
	mixed = (tmpA * alpha) + (tmpB * (32 - alpha));
	return ((mixed >> 5) & 0x7C1F) | ((mixed >> 20) & 0x03E0);
}

We now generate:
_Trans16Bit:
.LBB_Trans16Bit_0:      ; entry
        andi. r2, r4, 31775
        rlwimi r2, r4, 15, 7, 11
        subfic r4, r5, 32
        mullw r2, r2, r4
        andi. r4, r3, 31775
        rlwimi r4, r3, 15, 7, 11
        mullw r3, r4, r5
        add r2, r2, r3
        srwi r3, r2, 5
        andi. r3, r3, 31775
        rlwimi r3, r2, 12, 22, 26
        blr

Instead of:
_Trans16Bit:
.LBB_Trans16Bit_0:      ; entry
        slwi r2, r4, 15
        rlwinm r2, r2, 0, 7, 11
        andi. r4, r4, 31775
        or r2, r2, r4
        subfic r4, r5, 32
        mullw r2, r2, r4

        rlwinm r4, r4, 0, 7, 11

        andi. r3, r3, 31775

6d2e334cce We also have V8, so do not force every Sparc to be treated like a V9. It is
still possible to force V9 (even if configure doesn't think it's one) via
``./configure --target=sparcv9-sun-solaris2.8'' so nothing is lost.

The issue is there is no unsigned -> double conversion, only signed.  So I

this should be in a different BB, but in the mean time, I use a branch

45eeed9b35 Two dist-check related changes:
1. Allow DIST_CHECK_CONFIG_OPTION to specify a set of options to be passed
   to the configure script during the dist-check target. This allows things
   to be passed down on a project basis so the configure doesn't fail.

2. Use the tar | (cd ; tar ) idiom to copy files which is more flexible
   than using the cp command. THis allows us to exclude CVS .svn
   directories at source rather than stripping them out of the tar ball.
