This header already includes a CodeGen header and is implemented in
lib/CodeGen, so move the header there to match.
This fixes a link error with modular codegeneration builds - where a
header and its implementation are circularly dependent and so need to be
in the same library, not split between two like this.

The liveness-tracking code assumes that the registers that were saved
in the function's prolog are live outside of the function. Specifically,

This isn't always the case as illustrated by the LR register on ARM.

It defined the LLVM_AVR_GCC_COMPAT constant, which would enable/disable
certain GCC-specific behaviours.
There is no point conditionally turning it on/off, as it will always be
turned on, and we have to maintain both code paths anyway.
