[PATCH] BaseTools/tools_def AARCH64: enable frame pointers for RELEASE builds

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

Commit 8f0b62a5dac0 ("BaseTools/tools_def AARCH64: enable frame pointers
for DEBUG builds") removed the -fomit-frame-pointer switch from the
shared CFLAGS between AARCH64 DEBUG and RELEASE build, and move it to
the RELEASE specific ones, so that DEBUG builds can produce a backtrace
when a crash occurs.

This is actually a useful thing to have for RELEASE builds as well.
AArch64 has 30 general purpose registers, and so the performance hit of
having a frame pointer is unlikely to be noticeable, nor are the
additional 8 bytes of stack space likely to present a problem.

So remove -fomit-frame-pointer altogether this time.
