picking registers like SIL just because ESI was being used.

Just because an alias of a register is available, it doesn't mean that we
can arbitrarily evict the register.

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

The vector may actually be empty if the register that we are marking as
recently used is not actually allocatable.  This happens for physical registers
that are not allocatable, like the ST(x) registers on X86.
