proc.c (rb_proc_alloc): inline and move to vm.c

* proc.c (rb_proc_alloc): inline and move to vm.c
  (rb_proc_wrap): new wrapper function used by rb_proc_alloc
  (proc_dup): simplify alloc + copy + wrap operation
  [ruby-core:64994]

* vm.c (rb_proc_alloc): new inline function
  (rb_vm_make_proc): call rb_proc_alloc

* vm_core.h: remove rb_proc_alloc, add rb_proc_wrap

* benchmark/bm_vm2_newlambda.rb: short test to show difference

First we allocate and populate an rb_proc_t struct inline to avoid
unnecessary zeroing of the large struct.  Inlining speeds up callers as
this takes many parameters to ensure correctness.  We then call the new
rb_proc_wrap function to create the object.

rb_proc_wrap - wraps a rb_proc_t pointer as a Ruby object, but
we only use it inside rb_proc_alloc.  We must call this before
the compiler may clobber VALUE parameters passed to rb_proc_alloc.
