than the type an i1 is promoted to (eg: i8).  Account
for this.  Noticed by Tilmann Scheller on CellSPU; he
will hopefully take care of fixing this in LegalizeDAG
and adding a testcase!

Why?  Because it was there!

It turns out that this is a fairly common operation,
and it's easy enough to handle.

This is a temporary solution to help with the block rewriter (though it certainly has general utility).
Once DeclGroup's are implemented, this SourceLocation should be stored with it (since it applies to all the decls).

 - Enabled for builtins which are always constant expressions
   (__builtin_huge_val*, __builtin_inf*, __builtin_constant_p,
   __builtin_classify_type, __builtin___CFStringMakeConstantString).

Added Builtin::Context::isConstantExpr.
 - Currently overly simply interface which only works for builtins
   whose constantexprness does not depend on their arguments.

CallExpr::isBuiltinConstantExpr now takes an ASTContext argument.

runnable on the build machine.

There are a few bits that need built for the build environment (TableGen).
This patch builds those bits, and the associated libraries, for the build
environment as well as the (usual) host environment.

Thanks to Eric C. and Devang P. for pre-commit review.

sequences like this:
       sete    %al
       testb   %al, %al
       jne     LBB11_1

can be used when deciding if a block can transfer control to another
via a fall-through instead of a branch.

Plugins can be now compiled in with a slight Makefile change.
For example, to compile the new Clang driver, use:

cd $LLVMC2_DIR
make TOOLNAME=ccc2 BUILTIN_PLUGINS=Clang

Use a multimap rather than a map for holding the list of copies to insert, so we don't lose copies when two of them have
the same source.  I don't know what I was thinking when I wrote this originally.
Note: There's probably a more efficient way to do this, but I need to think about it some more, and about what determinism
guarantees need to be present.

This commit also includes some name changes in the blocks rewriter (no functionality change).
