In order to apply that, we're now doing explicit EnvToInt64 call as
part of initializing thread cache module.

These came in from the Google-internal version of tcmalloc. They saw some
decent speed improvements, both on microbenchmarks and big programs. The
idea is to improve the speed of the "Is everything initialized?" type of
code, that's at the start of all allocations and deallocations.

cygwin, that went away when I turned off tls support. Since I
didn't use to have such problems, I am being conservative and
only turning off TLS for the particular version of cygwin I'm
testing on (as returned by uname()).
