where the handle bus errors) also, clear the signal mask so that the
signal doesn't infinitely reissue.  This fixes rdar://6654827 -

1. When the JIT is asked to remove a function, updating it's
   mapping to 0, we invalidate any function stubs used only 
   by that function.  Now, also invalidate the JIT's mapping
   from the GV the stub pointed to, to the address of the GV.

2. When dlsym stubs for cross-process JIT are enabled, do not
   abort just because a named function cannot be found in the
   JIT's process.

3. Fix various assumptions about when it is ok to use the lazy
   resolver when non-lazy JITing is enabled.

the same say the "test" instruction does in overflow cases,
so eliminating the test is only safe when those bits aren't
needed, as is the case for COND_E and COND_NE, or if it
can be proven that no overflow will occur. For now, just
restrict the optimization to COND_E and COND_NE and don't
do any overflow analysis.

If ARCH is x86_64, pass -m64 to the host compiler. -m32 for i386. This makes sure the JIT work correctly.

to find a tiny mouse hole to squeeze through, it struck
me that globals without a name can be considered internal
since they can't be referenced from outside the current
module.  This patch makes GlobalOpt give them internal
linkage.  Also done for aliases even though they always
have names, since in my opinion anonymous aliases should
be allowed for consistency with global variables and
functions.  So if that happens one day, this code is ready!

get nice and happy stack traces when we crash in an optimizer or codegen.  For
example, an abort put in UnswitchLoops now looks like this:

Stack dump:
0.	Program arguments: clang pr3399.c -S -O3 
1.	<eof> parser at end of file
2.	per-module optimization passes
3.	Running pass 'CallGraph Pass Manager' on module 'pr3399.c'.
4.	Running pass 'Loop Pass Manager' on function '@foo'
5.	Running pass 'Unswitch loops' on basic block '%for.inc'
