David Mosberger-Tang cbd8648b33 Make libunwind compile with recent versions of GAS.
Don't test read-only access to F0 and F1 registers --- according to
the SCRA manual, those locations cannot even be expressed in SPILL
descriptors and newer versions of GAS (as well as IAS) won't accept
.spillreg directives targeting those registers.
