rs6000: Fix for -mwarn-cell-microcode (PR43763)

If using -mwarn-cell-microcode, rs6000_final_prescan_insn calls
get_insn_template to get the name of the machine instruction.  But,
get_insn_template calls the output template if that is code, and that
then can modify recog_data (it is normal to change the operands, for
example).

runtime: fix sigfwd to not allocate memory

    The use of &[1]uintptr{fn} was causing sigfwd to allocate memory, even
    though it is being compiled for the runtime package.  That is a bad
    idea for this function, which is invoked by a signal handler.  Rewrite
    it to use only constructs that do not allocate memory when compiled
    for the runtime package.

    The test for this is misc/cgo/testcarchive in the main repo, which we

[ARM] Fix PR79742 incorrect scheduler choice.

Due to an oversight, the changes to use the new CPU generation tables
forgot to handle selecting a scheduler for a CPU other than the named
CPU target.  This meant that if, say, cortex-a12 was used, the null
scheduler was chosen rather than cortex-a17's scheduler as intended.
The fix is to correctly use the 'tune for' field when generating the
target-specific data files.

This revealed a spelling mistake in the name of the tune target in
