TI has clarified [1] that R3.w0 is caller saved, so allow compiler to
use it. This is safe change because older GCC versions treat R3.w0 as
fixed register and never use it.

One of the changes frees a previously fixed register, per
ABI clarification from TI, for local usage from function.
The change is backwards compatible.
Rest of changes are cleanups.
Testsuite did not reveal any regressions.
