input the the mul is a zext from bool, just that it is all zeros
other than the low bit.  This fixes some phase ordering issues
that would cause us to miss some xforms in mul.ll when the worklist
is visited differently.

end of the function in the first path.  This greatly speeds up
some pathological cases (e.g. PR5150).

For now the metadata of sinked/hoisted instructions is still wrong, but that'll
be fixed when instructions will have debug metadata directly attached.

Implement proper asmprinting for the globals. This eliminates bogus "call" modifier and also adds support for offsets wrt globals.

- llvm's libs must be linked after clang's
- libLLVMSystem depends on psapi on win32 (get_system_libs has it)
- CIndex builds successfully on mingw now

default binding for regions. This allows us to simply a lot of code. A
further simplification could be done is that many methods of
regionstore can only work on Store instead of GRState.

done by condprop, but do it in a much more general form.  The
basic idea is that we can do a limited form of tail duplication
in the case when we have a branch on a phi.  Moving the branch
up in to the predecessor block makes instruction selection
much easier and encourages chained jump threadings.
