For PR950:
...
Retain the signedness of the old integer types in a new TypeInfo structure
so that it can be used in the grammar to implement auto-upgrade of things
that depended on signedness of types. This doesn't implement any new
functionality in the AsmParser, its just plumbing for future changes.

Minor code layout tweak: if we have something like this:
...
if (cond) goto BB2
BB1:
...
return;
BB2:
...
Move BB1 to the end of the function so that the code falls through in the
non-return case. This has the effect of moving assert (and other no-return
call) bodies and return blocks out of loops.

Rewrite the branch selector to be correct in the face of large functions.
...
The algorithm it used before wasn't 100% correct, we now use an iterative
expansion model. This fixes assembler errors when compiling 403.gcc with
tail merging enabled.
Change the way the branch selector works overall: Now, the isel generates
PPC::BCC instructions (as it used to) directly, and these BCC instructions
are emitted to the output or jitted directly if branches don't need
expansion. Only if branches need expansion are instructions rewritten
and created. This should make branch select faster, and eliminates the
Bxx instructions from the .td file.
