Tired of wading through cvs's list ? files that are generated when building
with srcdir = objdir to see what's okay and what's cruft. So, in goes a

"make check".

Update to llvm-config tool, by Erik Kidd:

1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
4. Document the tool with a POD file.

This version is now ready for testing by users.

A little script to find LLVM symbols. Ideally this would use c++filt for

the desired symbol.

Add a hacky workaround for crashes due to vectors live across blocks.
Note that this code won't work for vectors that aren't legal on the
target.  Improvements coming.

Print absolute memory references like this:

       lwz r2, 8(0)
instead of this:
       lwz r2, 8(r0)

This fixes the llc/llc-beta failures on PPC last night.

- Remove scalar to vector pseudo ops. They are just wrong.
- Handle FR32 to VR128:v4f32 and FR64 to VR128:v2f64 with aliases of MOVAPS
and MOVAPD. Mark them as move instructions and *hope* they will be deleted.

minor code simplification

With Evan's latest tblgen patch, this code is obsolete, thanks Evan!

Cause the various warnings list to be generated via a <ul> list with
text enclosed in <tt>. This ensures that (a) the text is in a fixed width
font (to indicated generated text) and (b) the text wraps without causing
the page width to be extended. The main result of this is that the report
will wrap to conform to the window size in which it is displayed instead of
having a very wide length if a warning message is long.

Handle constant addresses more efficiently, folding the low bits into the
