This deletes most HAVE_AS_* that determine if the assembler supports
some ISA level (and also HAVE_AS_MFPGPR and HAVE_AS_DFP).
These are not useful: we will only generate an instruction that requires
some newer ISA if the user specifically asked for it (with -mcpu=, say).
If the assembler cannot handle that, it is fine if it gives an error.
They also hurt: it increases the number of possible situations that all
need handling and all need testing. We do not handle all cases, and
obviously do not test all either.

In C11, implicit conversions from integer to floating-point types
produce results with the range and precision of the corresponding
evaluation format rather than only those of the type implicitly
converted to. This patch implements that case of C11 excess precision
semantics in the case of a comparison between integer and
floating-point types, previously missed when implementing other cases
of excess precision for such implicit conversions. As with other such
fixes, this patch conservatively follows the reading of C99 where
conversions from integer to floating-point do not produce results with
excess precision and so the change is made for C11 mode only.
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

This patch reimplements the handling of the secondary stack when the
iteration scheme of a loop statement requires this support.
Prior to this modification, an iterator loop over a container was
assumed to require unconditional secondary stack management. This is
however not always true because of user-defined iterator types, where
routines First and Next return an iterator that does require the
secondary stack.
