Due to config.gcc all the options need to be on one line because of the grep
lines which would select only the first line of the option.

This causes it not to select the right bits on options that are spread over
multiple lines when the --with-arch configure option is used.  The issue happens
silently and you just get a compiler with an incorrect set of default flags.

The current rules are quite rigid:

   1) No space between the AARCH64_OPT_EXTENSION and the opening (.
   2) No space between the opening ( and the extension name.
   3) No space after the extension name before the ,.
   4) Spaces are only allowed after a , and around |.

This patch makes this a lot less fragile by using the C pre-processor to flatten
the list and then provides much more flexible regex using group matching to
process the options instead of string replacement.  This removes all the
restrictions above and makes the code a bit more readable.

gcc/ChangeLog:

	PR target/89517
	* config.gcc: Relax parsing of AARCH64_OPT_EXTENSION.
	* config/aarch64/aarch64-option-extensions.def: Add new comments
	and restore easier to read options.

This patch moves part of the type conversion code from convert.c to match.pd
because match.pd is able to apply these transformations in the presence of
intermediate temporary variables.

Concretely it makes both these cases behave the same

  float e = (float)a * (float)b;
  *c = (_Float16)e;

and 

  *c = (_Float16)((float)a * (float)b);

The testcase is failing to instrument part of the source because of a bug
in the ordering of static DTORs.  It seems unlikely that this is generically
fixable in the toolchain (and given that it's likely to be a dynamic loader
change would not be expected to be applied retrospectively to OS versions
that are out of support).  To avoid the testsuite noise, xfail the count lines
that don't match (we can adjust the xfails as/when the upstream bug is fixed).

dejagnu xfails do not seem to work when embedded in a line like:
  ~Test (void) { .... /* count(1) { xfail ... } */ }
the closing brace seems to confuse the parser.  The solution is to exapnd the
text onto three lines.

The Thumb-2 movsi patterns try to prefer low registers for loads and stores.
However this is done incorrectly by using 2 separate variants with 'l' and 'h'
register classes.  The register allocator will only use low registers, and
as a result we end up with significantly more spills and moves to high
registers.  Fix this by merging the alternatives and use 'l*r' to indicate
preference for low registers.  This saves ~400 instructions from the pr77308
testcase.

When entering an interrupt, not only the call save registers needs to
be place on stack but also the call clobbers one. More over, the
ARC700 return from interrupt instruction needs to be rtie, the same
like ARCv2 CPUs. While the ARC6xx family uses j.f [ilinkX]
instruction. Additionally, we need to save the state of the ZOL
machinery, namely the lp_count, lp_end and lp_start registers. For
architectures which are using extension registers (i.e., HS48) we need
to save/restore them as well.
