Nikhil Benesch e496e612b7 runtime: never call into race detector with retaken P ... cgocall could previously invoke the race detector on an M whose P had been retaken. The race detector would attempt to use the P-local state from this stale P, racing with the thread that was actually wired to that P. The result was memory corruption of ThreadSanitizer's internal data structures that presented as hard-to-understand assertion failures and segfaults. Reorder cgocall so that it always acquires a P before invoking the race detector, and add a test that stresses the interaction between cgo and the race detector to protect against future bugs of this kind. Fixes #27660.
