Regenerated with autoconf-2.57.

Only default to the llvm-gcc in ~lattner if that directory exists.
Only warn if python version is not right; don't abort.
Add sanity checks for --with-llvmgccdir, with a big warning message at the end.

As per PR96, don't build subdirs if LLVMGCCDIR is not set to something
reasonable, instead, print out a "LOUD warning".

Stylesheets: they do a website good!

Implement a small optimization to handling of GEP's that are equivalent to casts.
This results in substantially reduced collapsing for some testcases

I can't believe the incompetence of the people I have to deal with around here.
These fools don't even wrap code at 80 columns.

Oh wait, _I_ wrote that.  That explains a lot!!

Bugz come in, bugs go out

Fix PR 110: the constant folding code assumes that if something is not a
constant expression, but is of (for example) ubyte type, then it is a
ConstantUInt.  This was not true for placeholders.

This is obviously illegal C++ code, but was apparently accepted by 3.3

Give props to Reid Spencer for the namespacification work.

As the comments indicate, this is a temporary, repulsive, hack
