23e2ac8894 remove DebugIterations option. Despite the accusations, 
jump threading has been shown to only expose problems not
have bugs itself.  I'm sure it's completely bug free! ;-)

c0280e8867 Move the conversion to intptr_t to a separate statement. This

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.

7a56e66e32 Enable the Clang plugin by default. 
This will eventually replace `ccc`. The command `llvmc -clang` now uses
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.
