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.

This adds an implementation of the insn_cost hook to rs6000.

This implementations is very minimal (so far).  It is mostly based on
how many machine instructions are generated by an RTL insn, and it also
looks at the instruction type.  Floating point insns are costed as if
all machine instructions it generates are floating point; the other
insns are treated as if all but one are integer insns (and one is the
specified type).  Load instructions are treated as costing twice as
much, and load locked and sync insns as three times as much (just like
the original costs), and integer div and mul are handled as well.

Each define_insn (etc.) can set a "cost" attribute to override this
general cost.  With optimization for size, the cost is set equal to the
value of the "length" attribute.

With this, the majority of cost differences between old and new are
where the old was wrong.  Also, benchmarks show a slight win (if
anything).  Some refinements are obviously needed.
