support builtin features with Ruby and C. Support loading builtin features written in Ruby, which implement with C builtin functions. [Feature #16254] Several features: (1) Load .rb file at boottime with native binary. Now, prelude.rb is loaded at boottime. However, this file is contained into the interpreter as a text format and we need to compile it. This patch contains a feature to load from binary format. (2) __builtin_func() in Ruby call func() written in C. In Ruby file, we can write `__builtin_func()` like method call. However this is not a method call, but special syntax to call a function `func()` written in C. C functions should be defined in a file (same compile unit) which load this .rb file. Functions (`func` in above example) should be defined with (a) 1st parameter: rb_execution_context_t *ec (b) rest parameters (0 to 15). (c) VALUE return type. This is very similar requirements for functions used by rb_define_method(), however `rb_execution_context_t *ec` is new requirement. (3) automatic C code generation from .rb files. tool/mk_builtin_loader.rb creates a C code to load .rb files needed by miniruby and ruby command. This script is run by BASERUBY, so *.rb should be written in BASERUBY compatbile syntax. This script load a .rb file and find all of __builtin_ prefix method calls, and generate a part of C code to export functions. tool/mk_builtin_binary.rb creates a C code which contains binary compiled Ruby files needed by ruby command.

__builtin_inline! Add an experimental `__builtin_inline!(c_expression)` special intrinsic which run a C code snippet. In `c_expression`, you can access the following variables: * ec (rb_execution_context_t *) * self (const VALUE) * local variables (const VALUE) Not that you can read these variables, but you can not write them. You need to return from this expression and return value will be a result of __builtin_inline!(). Examples: `def foo(x) __builtin_inline!('return rb_p(x);'); end` calls `p(x)`. `def double(x) __builtin_inline!('return INT2NUM(NUM2INT(x) * 2);')` returns x*2.
