Treat discarding array initializer elements as an extwarn (so -pedantic-errors flags it). Allow CodeGen to truncate the initializer if needed.

Also change a codegen warning to dump to stderr so it doesn't
mess with -emit-llvm output

We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.

chooses CodeGen type names.

This means that "typedef struct {...} foo" now results in a CodeGen name of 
"struct.foo" rather than "struct."

into alias analysis.  This meant updating the API
which now has versions of the getModRefBehavior,
doesNotAccessMemory and onlyReadsMemory methods
which take a callsite parameter.  These should be
used unless the callsite is not known, since in
general they can do a better job than the versions
that take a function.  Also, users should no longer
call the version of getModRefBehavior that takes
both a function and a callsite.  To reduce the
chance of misuse it is now protected.

Added optimization to the serialization of SelectorTable where we only serialize
out MultiKeywordSelectors that are ever referenced by an object other than the
SelectorTable.
