Fix 'ISO C90 forbids mixed declarations and code' compiler warning

* pthread_support.c [GC_PTHREADS && !GC_WIN32_THREADS]
(GC_thread_exit_proc): Move GC_log_printf() call down to be after local
variables declarations.
* thread_local_alloc.c [THREAD_LOCAL_ALLOC && USE_PTHREAD_SPECIFIC
&& !USE_WIN32_SPECIFIC]: Add {} to have "k" local variable declaration
before any statement in a block.
