2021-10-20	YJIT: Show GCC that the mmap probing loop runs at least once	Alan Wu
	Fixes: ./src/yjit_asm.c:196:8: warning: 'mem_block' may be used uninitialized [-Wmaybe-uninitialized]
2021-10-20	Fix non RUBY_DEBUG build warnings	Alan Wu
	On non RUBY_DEBUG builds, assert() compiles to nothing and the compiler warns about uninitialized variables in those code paths. Replace those asserts with rb_bug() to fix the warnings and do the assert in all builds. Since yjit_asm_tests.c compiles outside of Ruby, it needed a distinct version of rb_bug(). Also put YJIT_STATS check for function delcaration that is only defined in YJIT_STATS builds.
2021-10-20	Put YJIT into a single compilation unit	Alan Wu
	For upstreaming, we want functions we export either prefixed with "rb_" or made static. Historically we haven't been following this rule, so we were "leaking" a lot of symbols as `make leak-globals` would tell us. This change unifies everything YJIT into a single compilation unit, yjit.o, and makes everything unprefixed static to pass `make leak-globals`. This manual "unified build" setup is similar to that of vm.o. Having everything in one compilation unit allows static functions to be visible across YJIT files and removes the need for declarations in headers in some cases. Unnecessary declarations were removed. Other changes of note: - switched to MJIT_SYMBOL_EXPORT_BEGIN which indicates stuff as being off limits for native extensions - the first include of each YJIT file is change to be "internal.h" - undefined MAP_STACK before explicitly redefining it since it collide's with a definition in system headers. Consider renaming?

2021-10-20	style: switch statements indent	Alan Wu
	Case labels get half an indent and the opening brace is on the same line as "switch".
