    • [AArch64][2/2] Add sve_width -moverride tunable · 886f092f 
      On top of the previous patch that implements TARGET_ESTIMATED_POLY_VALUE
and adds an sve_width tuning field to the CPU structs, this patch implements
an -moverride knob to adjust this sve_width field to allow for experimentation.
Again, reminder that this only has an effect when compiling for VLA-SVE that is,
without msve-vector-bits=<foo>. This just adjusts tuning heuristics in the compiler,,
like profitability thresholds for vectorised versioned loops, and others.

It can be used, for example like -moverride=sve_width=256 to set the sve_width
tuning field to 256. Widths outside of the accepted SVE widths [128 - 2048] are rejected
as you'd expect.

    * config/aarch64/aarch64.c (aarch64_tuning_override_functions): Add
    sve_width entry.
    (aarch64_parse_sve_width_string): Define.


    * gcc.target/aarch64/sve/override_sve_width_1.c: New test.

    • [AArch64][1/2] Implement TARGET_ESTIMATED_POLY_VALUE · 2d56d6ba 
      The hook TARGET_ESTIMATED_POLY_VALUE allows a target to give an estimate for a poly_int run-time value.
It is used exclusively in tuning decisions, things like estimated loop iterations, probabilities etc.
It is not relied on for correctness.

If we know the SVE width implemented in hardware we can make more more
informed decisions in the implementation of TARGET_ESTIMATED_POLY_VALUE,
even when compiling for VLA vectorisation.

This patch adds an sve_width field to our tuning structs and sets it for
the current CPU tunings.

A new value is introduced to the aarch64_sve_vector_bits_enum enum that indicates
that SVE is not available: SVE_NOT_IMPLEMENTED. I set it to the same value as SVE_SCALABLE
so that parts of the aarch64 backend that follow the pattern:
if (vector_width == SVE_SCALABLE)
  do_vla_friendly_action ()
else
  assume_specific_width_for_correctness ()

continue to work without change, but the CPU tuning structs can use a more
appropriate moniker for indicating the absence of SVE.

This sets sve_width to SVE_NOT_IMPLEMENTED for all cores.
I aim to add an -moverride switch in the next patch that allows a power user to experiment
with different values of it for investigations.

	* config/aarch64/aarch64-opts.h (aarch64_sve_vector_bits_enum):
	Add SVE_NOT_IMPLEMENTED value.
	* config/aarch64/aarch64-protos.h (struct tune_params): Add sve_width
