The tsan13 test highlighted a few bugs. The first being runtime.sigprofNonGoWrapper was being called from C code and violating the C ABI. The second was a missed tsan acquire/release after thread creation. The third was runtime.cgoSigtramp violating ELFv2 ABI constraints when loading g. It is reworked to avoid clobbering R30 and R31 via runtime.load_g.
