Revert the addition of hasNoPointerOverflow to GEPOperator.
...
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.
Remove a few optimizations that depended on this flag.

Add plumbing for the `linker_private' linkage type. This type is meant for

"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.
This is plumbing, so we don't have a use of it yet. More to come, etc.

Switch Alpha over to the new call lowering style. New code mostly

copied from the SystemZ target. I don't think this causes any
significant changes to the output (I compared the assembly, and the
results appeared to be essentially unchanged), although I don't actually
have an Alpha to test on.
I would appreciate if anyone with the appropriate hardware could test
this. I'm not sure if that includes anyone subscribed to llvm-commits,
though.
