de39a12610 Revert r82404, it is causing a bootstrap miscompile. This is very very 
scary, as it indicates a lurking bug. yay.

a9a2b9a4cc 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.

b7d34131d1 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.

6bae20046f 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.

3a20fca97c don't use count + insert, just do insert + failure. Also, instead of deleting from 
the middle of a vector, swap the last element in and pop_back.  Also saves 330 bytes :)

6a6a75896d 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.
