Constantly forking a single-threaded process in a loop leads to
a memory leak when using POSIX timers.
==> fork_leapfrog.rb <==
require 'io/wait'
Dir.chdir '/proc'
prev = 0
loop do
pid = fork
exit!(0) if pid
# show the number of 4K pages used (Linux-only)
n = File.read("#$$/statm").split(-' ')[1].to_i
if n > prev
puts "#{prev} => #{n}"
prev = n
end
# since Ctrl-C from a terminal can't stop this loop,
# allow the user to just hit any key to stop
break if STDIN.wait(0)
end

Give the whole MJIT header path name by preloaded shared library
mjit_build_dir.so, than building the path from a given directory
name and the embedded base name.

* spec/ruby/library/win32ole/fixtures/classes.rb: add
SYSTEM_MONITOR_CONTROL_AVAILABLE.
* spec/ruby/library/win32ole/win32ole_method/event_spec.rb: Internet
Explorer is not available in some environment. Instead, try to use
System Monitor Control.

In regparse.c, in function node_extended_grapheme_cluster,
we used a raw if() with exit(1) as a cross-check for our
length calculations for the common node array. Convert this
to an assertion and comment it out because it is not needed
for active code.

Apparently, a component of Rails implements a buffering .write
method which keeps the String buffer around and makes it unsafe
for us to clear it after calling .write.
This caused Rack::Deflater to give empty results when enabled.
Fortunately, per r61631 / a55abcc0ca,
this misguided optimization was only worth a small (0.5MB) savings
and we still benefit from the majority of the memory savings in
that change.
Thanks to zunda for the bug report.

In file regparse.c, in function node_extended_grapheme_cluster(),
eliminate code duplication of CRLF and '.' (any character). This
uses the fact that both for Unicode encodings and for non-Unicode
encodings, the first alternative is CRLF, and the last alternative
is '.' (any character). This puts all of the pieces into forward
order (the order of the code follows the order of the syntax
definition).

* vm_trace.c: add `script_compiled` event. This event invoked
after script compiling and before evaluating compiled script.
Also the following methods are added:
`TracePoint#compiled_instruction_sequence` method to get compiled
`RubyVM::InstructionSequence` instance.
`TracePoint#compiled_eval_script` method to get compiled script (String)
by *eval methods (return nil if compiling by file).
* vm_trace.c (tracepoint_attr_raised_exception):

* iseq.c: before this patch, RubyVM::InstructionSequence.of(src) (ISeq in
short) returns different ISeq (wrapper) objects point to one ISeq internal
object. This patch changes this behavior to cache created ISeq (wrapper)
objects and return same ISeq object for an internal ISeq object.
* iseq.h (ISEQ_EXECUTABLE_P): introduced to check executable ISeq objects.
* iseq.h (ISEQ_COMPILE_DATA_ALLOC): reordr setting flag line to avoid
ISEQ_USE_COMPILE_DATA but compiled_data == NULL case.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::wrapper` and
`rb_iseq_t::aux::exec`. Move `rb_iseq_t::local_hooks` to
`rb_iseq_t::aux::exec::local_hooks`.
* test/ruby/test_iseq.rb: add ISeq.of() tests.

There is no need to call this function twice in a row since
thread switching won't happen in-between calls to it.

Since io_fflush may block on mutex or rb_io_wait_readable and
switch threads, we need to ensure the `str' VALUE returned by
`rb_obj_as_string` is visible to GC.

regparse.c: In function node_extended_grapheme_cluster(), use function-global
array node_common and use it for list and alternate construction. This is done
so that in case of error, all nodes that have already been constructed can be
correctly freed in a single for loop. Document the layout structure.

Especially over checking argc then calling rb_scan_args just to
raise an ArgumentError.
