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."
