Remove global REG_SETs
We currently maintain global REG_SET versions of fixed_reg_set
and regs_invalidated_by_call. With bitmap_view, we can instead
operate directly on the underlying HARD_REG_SETs, avoiding the
need to keep the two pieces of data in sync.
I have a series of patches that removes the assumption that there's
a single global ABI for all functions in the translation unit,
which includes not relying on having a global regs_invalidated_by_call.
Removing the REG_SET equivalent is one step to doing that.
Note that the affected DF code is used for EH edges or dumping only,
so shouldn't be performance critical.
