This patch depends on the prior fix r129908 that changes to use std::find,
rather than std::binary_search, on unordered array.

These values were not used for anything. Spill size and alignment is a property
of the register class, not the register.

necessary since gcov counts transitions between blocks. It can't see if you've
run every line in a straight-line function, so we add an edge for it to notice.

TODO: we should emit slightly different .gcda files when .gcno emission is off.

TII::isTriviallyReMaterializable() shouldn't depend on any properties of the
register being defined by the instruction. Rematerialization is going to create
a new virtual register anyway.

On the x86-64 and thumb2 targets, some registers are more expensive to encode
than others in the same register class.

Add a CostPerUse field to the TableGen register description, and make it
available from TRI->getCostPerUse. This represents the cost of a REX prefix or a
32-bit instruction encoding required by choosing a high register.

Teach the greedy register allocator to prefer cheap registers for busy live
ranges (as indicated by spill weight).

     used by Clang.  To help Clang integration, the PTX target has been split
     into two targets: ptx32 and ptx64, depending on the desired pointer size.

- Add GCCBuiltin class to all intrinsics
- Split PTX target into ptx32 and ptx64

llvm is built with unsigned chars where an immediate such as 0xff would be zero
extended to 64-bits, turning "cmp $0xff,%eax" into
"cmp $0xffffffffffffffff,%eax".
