[PR67753] fix copy of PARALLEL entry_parm to CONCAT target_reg
In assign_parms_setup_block, the copy of args in PARALLELs from
entry_parm to stack_parm is deferred to the parm conversion insn seq,
but the copy from stack_parm to target_reg was inserted in the normal
copy seq, that is executed before the conversion insn seq. Oops.
We could do away with the need for an actual stack_parm in general,
which would have avoided the need for emitting the copy to target_reg
in the conversion seq, but at least on pa, due to the need for stack
to copy between SI and SF modes, it seems like using the reserved
stack slot is beneficial, so I put in logic to use a pre-reserved
stack slot when there is one, and emit the copy to target_reg in the
conversion seq if stack_parm was set up there.

* function.c (assign_parm_setup_block): Avoid allocating a
stack slot if we don't have an ABI-reserved one. Emit the
copy to target_reg in the conversion seq if the copy from
entry_parm is in it too. Don't use the conversion seq to copy
a PARALLEL to a REG or a CONCAT.

[Patch AArch64] Switch constant pools to separate rodata sections.
Now that PR63304 is fixed and we have an option to address
any part of the memory using adrp / add or adrp / ldr instructions
it makes sense to switch out literal pools into their own
mergeable sections by default.
This would mean that by default we could now start getting
the benefits of constant sharing across the board, potentially
improving code size. The other advantage of doing so, for the
security conscious is that this prevents intermingling of literal
pools with code.
Wilco's kindly done some performance measurements and suggests that
there is not really a performance regression in doing this.
I've looked at the code size for SPEC2k6 today at -Ofast and
in general there is a good code size improvement as expected
by sharing said constants.
Tested on aarch64-none-elf with no regressions and bootstrapped
and regression tested in my tree for a number of days now.

Move constant folds for maths functions to new file
The new routines operate on the built-in enum rather than on tree decls.
The idea is to extend this to handle internal functions too, with a
combined enum for both.
The patch also moves fold_fma too, with the same prototype. The long-term
plan is to replace FMA_EXPR with an internal function, for consistency
with the way that things like SQRT will be handled.
Tested on x86_64-linux-gnu, arm-linux-gnueabi and aarch64-linux-gnu.
