The current padding in the 'p' struct is hardcoded at 64 bytes. It should be the cache line size. On ppc64x, the current value is only okay because sys.CacheLineSize is wrong at 64 bytes. This change fixes that by making the padding equal to the cache line size. It also fixes the cache line size for ppc64/ppc64le to 128 bytes.

The go tool used to avoid passing -fsanitize=memory when building runtime/cgo. That was originally to avoid an msan error, but that error was fixed anyhow for issue #13815. And building runtime/cgo with -fsanitize=memory corrects the handling of the context traceback function when the traceback function itself is built with -fsanitize=memory.

Add support for writing TLS client random and master secret in NSS key log format. https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/Key_Log_Format Normally this is enabled by a developer debugging TLS based applications, especially HTTP/2, by setting the KeyLogWriter to an open file. The keys negotiated in handshake are then logged and can be used to decrypt TLS sessions e.g. in Wireshark. Applications may choose to add support similar to NSS where this is enabled by environment variable, but no such mechanism is built in to Go. Instead each application must explicitly enable. Fixes #13057.
