Enable sanitizers and profiler for aarch64-unknown-linux-musl

[alex]

This is pretty heavily cargo-culted, hopefully I didn't screw it up too badly.

Supported sanitizers also need to be declared in the target spec, for example:

rust/compiler/rustc_target/src/spec/x86_64_unknown_linux_musl.rs

Lines 10 to 14 in ba6f5e3

	base.supported_sanitizers = SanitizerSet::ADDRESS
	| SanitizerSet::CFI
	| SanitizerSet::LEAK
	| SanitizerSet::MEMORY
	| SanitizerSet::THREAD;

These commits modify compiler targets.
