[compiler-rt] Don't change g_tls_size after initialization.
Summary:
g_tls_size is not supposed to be changed after initialization. It's not
atomic, not guarded by a lock, nor thread_local. But it's read by
multiple threads.
The reason why it's mutated is mips and powerpc64 specific. We can
implement the same funcitonality without mutating g_tls_size.
I'm not sure how to write a test for this. Please advice. Thanks!
