add #include guard hack According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

split internal.h into files One day, I could not resist the way it was written. I finally started to make the code clean. This changeset is the beginning of a series of housekeeping commits. It is a simple refactoring; split internal.h into files, so that we can divide and concur in the upcoming commits. No lines of codes are either added or removed, except the obvious file headers/footers. The generated binary is identical to the one before.

internal/proc.h rework Annotated MJIT_FUNC_EXPORTED functions as such. Declaration of rb_sym_to_proc is moved into this file because the function is defined in proc.c rather than string.c.

VALUE rb_proc_location(VALUE self);
st_index_t rb_hash_proc(st_index_t hash, VALUE proc);
hash.c: Do not use the fast path (rb_yield_values) for lambda blocks As a semantics, Hash#each yields a 2-element array (pairs of keys and values). So, `{ a: 1 }.each(&->(k, v) { })` should raise an exception due to lambda's arity check. However, the optimization that avoids Array allocation by using rb_yield_values for blocks whose arity is more than 1 (introduced at b9d29603375d17c3d1d609d9662f50beaec61fa1 and some commits), seemed to overlook the lambda case, and wrongly allowed the code above to work. This change experimentally attempts to make it strict; now the code above raises an ArgumentError. This is an incompatible change; if the compatibility issue is bigger than our expectation, it may be reverted (until Ruby 3.0 release). [Bug #12706]
