386251341f improve memdep to eliminate bitcasts (and aliases, and noop geps)
early for the stated reasons: this allows it to find more 
equivalences and depend less on code layout.

771a5422e1 Move CoerceAvailableValueToLoadType earlier in GVN.cpp. Hook it up
so that nonlocal and partially redundant loads can use it as well.
The testcase shows examples of craziness this can handle.  This triggers
*many* times in 176.gcc.

bb6495cc67 enhance GVN to forward substitute a stored value to a load
(and load -> load) when the base pointers must alias but when
they are different types.  This occurs very very frequently in
176.gcc and other code that uses bitfields a lot.

b168737a74 Several changes together in a murky mess:
1. Change some "\n" -> '\n'.
2. eliminte some std::string's by using raw_ostream::indent.
3. move a bunch of code out of the main arg parser routine into
   a new static HandlePrefixedOrGroupedOption function.
4. Greatly simplify the implementation of getOptionPred, and make
   it avoid splitting prefix options at = when that doesn't match
   a non-prefix option.

5511ffd763 Here's fun! It turns out that these filter functions can be internal. If they're
internal, they shouldn't use the indirect pointer stuff. In the case of
throw_rethrow_test, it was marked as 'internal' and calculated its own offset to
its contents.
