everywhere it is used uses :GPR already, we can just as well use
TARGET_ISEL always.

This removes output_isel. Instead, the define_insn's now output the
isel instructions directly.
It adds a reg_or_zero operand predicate, too, because the reg_or_cint
predicate is too lax here. Also use it in the "reversed" variants of
the instructions.

Similar to other architectures with IFUNC binutils/glibc support, this
patch enables the ifunc attribute for ARM GNU/Linux. Although not
required for build master GLIBC, the intention is to allow refactor
its assembly implementation to C.
Tested compilation of glibc (in conjunction with a glibc patch to
support using the attribute on ARM) with build-many-glibcs.py (with
a patch to add a armv7 variant which enables multiarch). I have
not run the GCC tests for ARM.
