5026ae4514 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

f241174421 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.

3d10a5a757 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.

796492dc4b 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.

07598d72f0 Tweak cmake files for the four targets that don't split CodeGen out. 
- We should canonicalize this and get rid of the cmake and llvm-config hacks to
   support both variants.

- Shouldn't really be necessary, but currently .inc files get included into

2451a64687 Canonicalize bitcasts between types like <1 x i64> and i64 to 
insertelement/extractelement.

I'm not entirely sure this is precisely what we want to do: should we 
prefer bitcast(insertelement) or insertelement(bitcast)?  Similarly. should we 
prefer extractelement(bitcast) or bitcast(extractelement)?
