- A fix for the SPARC float handling. Adding the missing & to the field allows
the backend feature flag to be passed back which it was not without it.
- Add some patches to enable the integrated assembler on PowerPC / SPARC.
I left these out before as I thought because Clang was not obeying this
setting and had its own similar bits they were not necessary but turns
out the backend has some code that does obey this setting.
