Factor out division by squares
This patch implements the some of the division optimizations discussed in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71026.
The division reciprocal optimization now handles divisions by squares:
x / (y * y) -> x * (1 / y) * (1 / y)
This requires at least one more division by y before it triggers - the
3 divisions of (1/ y) are then CSEd into a single division. Overall
this changes 1 division into 1 multiply, which is generally much faster.

This patch moves the calculation of costs for MEM into a

Fix .debug_rnglists generation with -gdwarf-5 -gsplit-dwarf.
Early debug broke generation of .debug_rnglists when using both -gdwarf5
and -gsplit-dwarf. It introduces a generation for init_sections_and_labels,
but doesn't account for the generation of up to 4 unique ranges labels,
two created in init_sections_and_labels and two in output_rnglists.
Fix this by passing generation to output_rnglists and creating 4 unique
labels per generation.
Without this fix using -gdwarf-5 -gsplit-dwarf could result in:
Error: symbol `.Ldebug_ranges2' is already defined

C/C++: fix quoting of "aka" typedef information (PR 62170)
PR 62170 describes a problem with how the quoting in pp_format
interacts with the "aka" information for typedefs in %qT for
the C family of frontends, and also now for %qH and %qI in the
C++ frontend: we print:
'Py_ssize_t* {aka int*}'
^^^^^^^^^^^^^^^^^^^^^^ colorized as "quote"
i.e.
'[START_COLOR]Py_ssize_t* {aka int*}[END_COLOR]'
when we should print:
'Py_ssize_t*' {aka 'int*'}
^^^^^^^^^^^ ^^^^ colorized as "quote"
i.e.
'[START_COLOR]Py_ssize_t*[END_COLOR]' {aka '[START_COLOR]int*[END_COLOR]'}
where the opening and closing quote characters and colorization are
added by the 'q' handling within pp_format.
This patch fixes the quoting by updating the %T handling in C and C++
and the %H/%I handling in C++ to insert the quoting appropriately.
It converts the "quote" param of the pp_format_decoder callback from
bool to bool *, allowing for the %T and %H/%I handlers to write
false back to it, to avoid printing the closing quote for the cases
like the above where the trailing closing quote isn't needed.
It introduces pp_begin_quote/pp_end_quote to simplify this. These
take a "bool show_color", rather than using "pp_show_color (pp)"
since cxx_pp's pp_show_color isn't currently initialized (since
cxx_initialize_diagnostics happens before diagnostic_color_init).

[ARM] Factor out CMSE register clearing code
Functions cmse_nonsecure_call_clear_caller_saved and
cmse_nonsecure_entry_clear_before_return both contain very similar code
to clear registers. What's worse, they differ slightly at times so if a
bug is found in one careful thoughts is needed to decide whether the
other function needs fixing too.
This commit addresses the situation by factoring the two pieces of code
into a new function. In doing so the code generated to clear VFP
registers in cmse_nonsecure_call now uses the same sequence as
cmse_nonsecure_entry functions. Tests expectation are thus updated
accordingly.

As part of r253256, cmse_nonsecure_entry_clear_before_return has been
