[PATCH] D37248: [XRay][compiler-rt][NFC] Refactor global TLS variables behind an accessor function.

[Dean Michael Berris via Phabricator via llvm-commits]

dberris created this revision.

This change hides all the initialization of thread_local variables used
by the XRay FDR mode implementation behind a function call. This makes
initialization of thread-local data to be done lazily, instead of
eagerly when they're done as globals. It also gives us an isolation
mechanism if/when we want to change the TLS implementation from using
the C++ thread_local keyword, for something more ad-hoc (potentialy
using pthread directly) on some platforms or set-ups where we cannot use
the C++ thread_local variables.
