14d4094968 Factor out the code for sign-extending/truncating gep indices
and use it in x86 address mode folding. Also, make
getRegForValue return 0 for illegal types even if it has a
ValueMap for them, because Argument values are put in the
ValueMap. This fixes PR3181.

7307ef0ba3 add another level of caching for non-local pointer queries, keeping
track of whether the CachedNonLocalPointerInfo for a block is specific
to a block.  If so, just return it without any pred scanning.  This is
good for a 6% speedup on GVN (when it uses this lookup method, which
it doesn't right now).

d6036b3791 Speed up getABITypeSize by turning a i64 mul and div into an
AND.  This is speedup on any reasonable target, but particularly
on 32-bit targets where this often turns into a libcall like udivdi3.

We know that alignments are a power of two but the compiler doesn't.

df0e24acce Generalize bugpoint's concept of a "safe" backend, and add options
to allow the "safe" backend to be run with a different path, and/or
with different command-line options.

This enables the following use cases:
 - bugpoint llc against an llc command from a different build
 - bugpoint llc against the same llc with different command-line options
 - and more...

Also, document the existing "custom" interpreter options.

42bd5cffc9 Use intptr_t instead of unsigned here, which is more appropriate
in a really obscure way, but more importantly has the side effect
of avoiding a GCC warning in the case that IntType is bool.

the Clang toolchain instead of `llvm-gcc`.

4522fd9b8a Try to guess when the auto-generated cl::Sink option should be marked 'extern'.
This would be much easier to do if the CommandLine library didn't use
global state. Global state is evil.

ad82419b46 Introduce a new MemDep::getNonLocalPointerDependency
method.  This will eventually take over load/store dep
queries from getNonLocalDependency.  For now it works
fine, but is incredibly slow because it does no caching.
Lets not switch GVN to use it until that is fixed :)

8e8a6b4ec3 push the "pointer case" up the analysis stack a bit. This causes
duplication of logic (in 2 places) to determine what pointer a 
load/store touches.  This will be addressed in a future commit.

dc8cf1fa91 a memdep query on a volatile load/store will always return
clobber with the current implementation.  Instead of returning
a "precise clobber" just return a fuzzy one.  This doesn't 
matter to any clients anyway and should speed up analysis time
very very slightly.
