192913e281 Change from using a stub function to a stub variable for passing to the 
IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.

2824da4738 More cleanups. Also, add a special case for updating PHI nodes, and 
reimplement getValueDominatingFunction to walk the DominanceTree rather than
just searching blindly.

72f42bbc9b For PR786: 
Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.

461bed2b75 Provide a simpler interface for getting a ConstantArray from a character

wants a terminating null or not. The default is "true" to retain the same

8949477ae4 Adjust the interface to ConstantArray::get. The previous 
implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.

write a devirtualizer (which I have and may commit one of these days).
