This patch gives GCC to use the accumulator VGPR registers on CDNA1 and
later architectures. The backend does not yet attempt to make use of the
matrix acceleration instructions, but the new registers are still useful
as fast space for register spills. And they can now be used in inline
assembly statements.
I haven't written a dedicated testcase for this - just building libgcc
and libgfortran seems to have thoroughly exercised the code paths involved.
I have a test run in progress - assuming that this doesn't find any
breakage, OK to commit?
