thread.c: micro-optimize thread create/join
* thread.c (struct join_arg): restructure and make smaller (thread_join_sleep): avoid timeofday() call if forever (thread_join): pass join_arg.delay directly (rb_thread_inspect_msg): remove, inline into rb_thread_inspect (rb_thread_inspect): reduce branching and string creation * thread_pthread.c (native_set_thread_name): create string directly to avoid reparsing. [Misc #10723] This reduces time in benchmark/bm_vm_thread_create_join.rb by a few percent. Minor improvements only: target 0: 2.1.5 (ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-linux]) target 1: trunk (ruby 2.3.0dev (2015-01-16 trunk 49282) [x86_64-linux]) target 2: built (ruby 2.3.0dev (2015-01-16 trunk 49282) [x86_64-linux]) benchmark results: minimum results in each 3 measurements. Execution time (sec) name 2.1.5 trunk built vm_thread_create_join 1.049 1.242 1.138 Speedup ratio: compare with the result of `2.1.5' (greater is better) name trunk built vm_thread_create_join 0.845 0.923 git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
