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

        subfic r4, r5, 32

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.

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.

C'mon everybody, let's modify X86JITInfo.cpp.  This time, we add <iostream>

Finally get the quoting right for both Unix and Windows for the llvmgcc and

Two changes to support building shared libraries that contain multiple

1. Permit the "JIT" special keyword on LLVMLIBS to be recognized when

2. If LINK_LIBS_IN_SHARED is set, the LLVMLIBS and USEDLIBS can be specified
   when linking a shared library and the libraries listed will be
   incorported into the shared library. THis is only used when the

Sometimes tab completion is *not* your friend. Added the wrong file, by
accident so now I'm correcting it. The script is userloc.pl not userloc.html

pretty tiny change (looks like adding the HP-UX detection and line number
changes to me)

Added a note about how the type can be omitted in call instructions.

Fixed some typos, spelling, etc.
