Enable frame pointers explicitly under ARM32.

Enable frame pointers explicitly under ARM32.

This replaces the quick-fix in crrev.com/2820803003, to address issues
with ARM32 builds when frame pointers are disabled.

This CL explicitly enables frame pointers in ARM32 builds, and pulls out
the ARM32 and ARM64 special-cases to be handling separately from Debug,
profiling and sanitizer build configurations, for clarity.
