A method which has keyword parameters has an implicit local variable
to specify which keywords are (un)specified.
vm_call_iseq_setup_kwparm_nokwarg() is special function to invoke
a ISeq method without any keyword arguments. However, it should
also initialize the special local var. Without this initialization,
the implicit lvar can points a freed (T_NONE) object.
miniruby load *.rb from srcdir. To specify file path,
tool/mk_builtin_loader.rb embed full path of each *.rb file.
However it prevent to pre-generation of required files for tarball.
This patch generate srcdir/*.rb from __FILE__ information.
Previously we were passing the memory_id. This was broken previously if
compaction was run (which changes the memory_id) and now that object_id
is a monotonically increasing number it was always broken.
This commit fixes this by defering removal from the object_id table
until finalizers have run (for objects with finalizers) and also copying
the SEEN_OBJ_ID flag onto the zombie objects.
Not sure what is happening, but spec/ruby/security/cve_2018_6914_spec.rb
fails on macOS.

I suspect that the state of a directory is weird immediately after it is
created (not writable or even world writable?). This change tries to
make sure that ENV["TMPDIR"] is actually used by Dir.tmpdir.
If there is a type mismatch between expected builtin function type
and actual function type, C compiler shows warning.
For example, `__builtin_func(1, 2)` expects
`func(rb_ec_t*, VALUE self, VALUE p1, VALUE p2)` function definition.
However, it is easy to overlook "warning" messages. So this patch
changes to stop compiling as an error if there is a mismatch.
IO#read/write_nonblock methods are defined in prelude.rb with
special private method __read/write_nonblock to reduce keyword
parameters overhead. We can move them into io.rb with builtin
functions.
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.
