Improve ergonomics for Address Sanitizer #20

Running Address Sanitizer, the go-to memory debugger, currently requires multiple workarounds:

All sanitizers are botched in the default build mode, you need to force rustc to use gold linker as a workaround (Regression on nightly since LLVM 8 upgrade: thread sanitizer doesn't compile anymore rust-lang/rust#53945)
ASAN produces "ODR violation" false positives which can be suppressed through the ASAN options mechanism (AddressSanitizer: odr-violation with zero size rust-lang/rust#41807)

This is a pretty bad state to be in, especially since this tooling is a requirement for detecting exploitable bugs in unsafe code.
