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

Add support for writing TLS client random and master secret

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.

It does not appear to be necessary, and it is not the order we want
when a module can be loaded at an arbitrary point during a program's
execution as a plugin. So reverse the order.
While here, make it safe to call typelinksinit multiple times.
