Merge branch 'always-use-thread-local'

Browse source 
Always use thread_local as we can rely on compiler TLS support working
under Windows 7 and later.

There are some known problems in MinGW thread local variable support,
but they only affect (obsolete) 32-bit builds and will hopefully be
fixed in this compiler soon.

See #22917.
