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
