Owen Anderson edadd3faee Revert my previous work on ArgumentPromotion. Further investigation has revealed these 
changes to be incorrect.  They just weren't showing up in any of our current testcases.

Chris Lattner 97614c86ce Split rotate matching code out to its own function. Make it stronger, by 
matching things like ((x >> c1) & c2) | ((x << c3) & c4) to (rot x, c5) & c6

Anton Korobeynikov d61d39ec53 Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

Chris Lattner 2f107cfc0d On Mac OS/X, make Process::PreventCoreFiles disable crash reporter for 
the process in addition to disabling core file emission.  This speeds up
bugpoint on default-configured macs by several orders of magnitude.
