Log Message:
gperftools: updated to 2.19.3

gperftools 2.19.3 is out!

This is another bug-fix release on top of 2.19.2. It updates the
vendored aw-backtrace.

With the previous version of aw-backtrace, we got broken backtraces on
aarch64 when gperftools was built with -fstack-protector-strong, which
is the default compiler setting on many distros, e.g. Ubuntu (see
https://github.com/gperftools/gperftools/issues/1653). This release
fixes that and related issues. aw-backtrace's own CI now also tests
builds with stack protector, hardening (-mbranch-protection or
-fcf-protection), without frame pointers, and, on x86-64,
x86-64-v3 builds (stack realignment).

Notable changes:

* aw-backtrace now has a small piece of assembly (aw-asm-x86_64.S and
  aw-asm-aarch64.S) that captures the exact pc, sp and frame pointer
  of aw_backtrace_full's own frame, so the backtrace starts from known
  values. It is used on both architectures. Previously, on aarch64, we
  guessed the stack pointer of the frame we started from, and that
  guess was the bug described above.

* aarch64: when a frame has no usable unwind info, aw-backtrace
  steps to the caller through the frame record (saved x29/x30). A
  frame record gives the caller's pc and frame pointer, but not its
  stack pointer. We used to guess the stack pointer; now it is
  treated as unknown until the caller's own unwind info makes it known
  again.

* aw-backtrace now steps through frames whose unwind info uses an
  unsupported DWARF expression via the fallback (frame record based on
  aarch64), instead of stopping the backtrace there. This fixes
  backtraces on aarch64 through functions with SVE stack slots.

* aarch64: aw-backtrace now understands the
  DW_CFA_AARCH64_negate_ra_state_with_pc unwind instruction, which
  clang emits with -mbranch-protection=pac-ret+pc. Previously, frames
  using it were handled by the fallback instead of their unwind info.

* the Bazel build now pulls aw-backtrace via git_override, since the
  needed version isn't in the BCR yet.
