Chris Lattner 680ae74885 Remove obsolete wording, the only exception a readnone function can throw 
is the empty set. :)  Thanks to Fritz for pointing this out.

Chris Lattner f031421afe be very explicit that readnone/readonly functions can't 
throw exceptions.

Evan Cheng 210fc62a91 In some rare cases, the register allocator can spill registers but end up not utilizing registers at all. The fundamental problem is linearscan's backtracking can end up freeing more than one allocated registers. However, reloads and restores might be folded into uses / defs and freed registers might not be used at all. 
VirtRegMap keeps track of allocations so it knows what's not used. As a horrible hack, the stack coloring can color spill slots with *free* registers. That is, it replace reload and spills with copies from and to the free register. It unfold instructions that load and store the spill slot and replace them with register using variants.

Not yet enabled. This is part 1. More coming.

Douglas Gregor cb5166211f Fix crash in source-line truncation code for diagnostic 
printing. Also, when we only need to truncate the line at the end,
make sure there is room for the ellipsis.

Daniel Dunbar 80b4eef686 Use ASTRecordLayout for computing ivar offsets instead of shadow 
struct.
 - We still need to do more lookup than necessary because ivars don't
   live in a reasonable DeclContext.

 - The only remaining client of the interface shadow struct is the
   ivar layout bitmap.
