FIX llvm-gcc bootstrap on x86_64 linux. If a virtual register is copied to a physical register, it's not necessarily defined by a copy. We have to watch out it doesn't clobber any sub-register that might be live during its live interval. If the live interval crosses a basic block, then it's not safe to check with the less conservative check (by scanning uses and defs) because it's possible a sub-register might be live out of the block.

If multiple compile units are seen then emit them independently. In other words, do not force all DIEs into first, whatever it is, compile unit. 

Note, multiple compile unit support is not well tested (it did not work correctly until now anyway.)

There might be more dead code, but with llvm-gcc bootstrap broken on linux x86-64 it is had to test :-(

Fix PR3241: Currently EmitCopyFromReg emits a copy from the physical register to a virtual register unless it requires an expensive cross class copy. That means we are only treating "expensive to copy" register dependency as physical register dependency.
Also future proof the scheduler to handle "normal" physical register dependencies. The code is not exercised yet.

compensation for turning off gcc's inliner.  This gets
us closer to the amount of inlining we were getting before.
It is not a win on everything, of course, but seems to
gain overall.

Instead the information is cached on construction and the cached flag used thereafter.
Introduced two predicates: isCall and isInvoke.
