9bb1be2eec Commit a small improvement that is already in the x86 and ia64 backends to 
not generate unnecessary register copies.  This improves compile time by
2-5% depending on the test.

a2f68cf0f9 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.

a88b91d681 For PR572: 
Undefine the PPC symbol which is defined by Linux/PPC (erroneously) so it
doesn't pollute the user namespace and clash with our namespace declarations.

47cd13d42a 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
        slwi r4, r3, 15
        rlwinm r4, r4, 0, 7, 11
        andi. r3, r3, 31775
        or r3, r4, r3
        mullw r3, r3, r5
        add r2, r2, r3
        srwi r3, r2, 5
        andi. r3, r3, 31775
        srwi r2, r2, 20
        rlwimi r3, r2, 0, 22, 26

fb764f1829 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.

4062a79a81 Fix 2005-05-12-Int64ToFP 
The issue is there is no unsigned -> double conversion, only signed.  So I
need to test the sign and do a different thing depending on it.  Ideally
this should be in a different BB, but in the mean time, I use a branch
free method.

e126c81722 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.

e2d15e6fe9 Finally get the quoting right for both Unix and Windows for the llvmgcc and 
llvmgxx programs. dejagnu doesn't understand single quote and we need to
pass double quotes through to the shell in order to escape blanks in the
paths. This patch uses \" to escape the quotes passed through to the shell.
Thanks to Aaron Gray for testing this out on cygwin.
