When -march=native is passed to host_detect_local_cpu to the backend,
it overrides all command lines after it. That means
$ gcc -march=native -march=skylake-avx512
is the treated as
$ gcc -march=skylake-avx512 -march=native
Prune joined switches with Negative and RejectNegative to allow
-march=skylake-avx512 to override previous -march=native on command-line.

In general the stack pointer was not handled for many SUBS/ADDS patterns in
aarch64.md.
Both the "extended register" and "immediate" forms allow the stack pointer to be
used as the source register, while no form allows the stack pointer for the
destination register.
The define_insn patterns generating ADDS/SUBS did not allow the stack pointer
for any operand, while the define_peephole2 patterns that generated RTX to be
matched by these patterns allowed the stack pointer for any operand.
The patterns are fixed by adding the 'k' constraint for the first source operand
to all define_insns that generate the ADDS/SUBS "extended register" and
"immediate" forms (but not the "shifted register" form).
In peephole optimizations, constraint strings are ignored (see "(gccint) C
Constraint Interface" info node in the documentation), so the decision to act or
not is based solely on the predicate and condition.
This patch introduces a new predicate "aarch64_general_reg" to be used in
define_peephole2 patterns where only GENERAL_REGS registers are acceptable and
uses that predicate in the peepholes that generate patterns for ADDS/SUBS.
Full bootstrap and regtest done on aarch64-none-linux-gnu.
Regression tests done on aarch64-none-linux-gnu and aarch64-none-elf cross
compiler.
OK for trunk?

While doing more testing I found a couple of issues with my BTI patches.
This patch fixes them:
1) Remove a reference to return address key. The original patch was written
based on a different not yet committed patch ([PATCH 3/3][GCC][AARCH64] Add
support for pointer authentication B key) and I missed out on cleaning this
up. This is hidden behind the configuration option and thus went unnoticed.
2) Add a missed case for adding the BTI instruction in thunk functions.
