Clemens Backes 97d39db4c7 [compiler] Simplify register state accesses 
The register state is accessed a lot in the mid-tier register allocator.
Instead of going through an accessor with a DCHECK, just access
directly. This makes stepping for debugging a lot easier, and will
result in an easy-to-debug nullptr access if the register state is not
initialized.
