From-SVN: r233853
When processing substitutions the operands are renumbered. To find a
free operand number the array used_operands_numbers is used.
Currently this array is used to assign new numbers before all the
RTXes in the vector have been processed. I did run into problems with
this for insns where a match_dup occurred in a later (use ...) operand
referring to an earlier operand (e.g. s390.md "setmem_long").
The patch splits the loop doing the processing into two in order to
have all the operand numbers collected already when assigning new
numbers.

This patch makes it a compile-time error for an internal-fn optab
to FAIL. There are certainly other optabs and patterns besides these
that aren't allowed to fail, but this at least deals with the immediate
point of controversy.
Tested normally on x86_64-linux-gnu. Also tested by building one
configuration per cpu directory. arc-elf and pdp11 didn't build
for unrelated reasons, but I checked that insn-emit.o built for
both without error.

Change "if (E) free (E);" to "free (E);" everywhere except in the
libgo/, intl/, zlib/ and classpath/ directories.
Also transform equivalent variants like
"if (E != NULL) free (E);" and allow an extra cast on the
argument to free. Otherwise, the tested and freed "E"
expressions must be identical, modulo white space.
