The CASE_VECTOR_SHORTEN_MODE query is missing some equals signs
which causes suboptimal codegen due to missed optimisation
opportunities. This patch also adds a test for thumb2
switch statements as none exist currently.

Hi Richard,
I committed this combined patch (with Cortex-A520) for trunk
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=cab53aae43cf94171b01320c08302e47a5daa391
Am I ok to commit just the Cortex-A510 half into gcc-12 and gcc-13.
Thanks,

This patch makes the following changes:
1) When calling a secure function from non-secure code then any arguments
smaller than 32-bits that are passed in registers are zero- or sign-extended.
2) After a non-secure function returns into secure code then any return value
smaller than 32-bits t

Adds a check to ensure that the input vector arguments
to a function are not variable length. Previously, only the
output vector of a function was checked.

Replace manual swapping idiom with std::swap in aarch64.cc
gcc/config/aarch64/aarch64.cc has a few manual swapping idioms of the form:
x = in0, in0 = in1, in1 = x;
The preferred way is using the standard:
std::swap (in0, in1);
We should just fix these to use std::swap.
