* Add opt_duparray_send insn to skip the allocation on `#include?`
If the method isn't going to modify the array we don't need to copy it.
This avoids the allocation / array copy for things like `[:a, :b].include?(x)`.
This adds a BOP for include? and tracks redefinition for it on Array.

* Update opt_newarray_send to support simple forms of include?(arg)
Similar to opt_duparray_send but for non-static arrays.

This commit introduces a new instruction `opt_newarray_send` which is
used when there is an array literal followed by either the `hash`,
`min`, or `max` method.
```
[a, b, c].hash
```
Will emit an `opt_newarray_send` instruction. This instruction falls
back to a method call if the "interested" method has been monkey
patched.
Here are some examples of the instructions generated:
```
$ ./miniruby --dump=insns -e '[@a, @b].max'
== disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE)
0000 getinstancevariable :@a, <is:0> ( 1)[Li]
0003 getinstancevariable :@b, <is:1>
0006 opt_newarray_send 2, :max
0009 leave
$ ./miniruby --dump=insns -e '[@a, @b].min'
== disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE)
0000 getinstancevariable :@a, <is:0> ( 1)[Li]
0003 getinstancevariable :@b, <is:1>
0006 opt_newarray_send 2, :min
0009 leave
$ ./miniruby --dump=insns -e '[@a, @b].hash'
== disasm: #<ISeq:<main>@-e:1 (1,0)-(1,13)> (catch: FALSE)
0000 getinstancevariable :@a, <is:0> ( 1)[Li]
0003 getinstancevariable :@b, <is:1>
0006 opt_newarray_send 2, :hash
0009 leave
```
[Feature #18897] [ruby-core:109147]
Co-authored-by: John Hawthorn <jhawthorn@github.com>
Given that signleton classes don't have an allocator,
we can re-use these bytes to store the attached object
in `rb_classext_struct` without making it larger.
On a hash miss we need to call default if it is redefined in order to
return the default value to be used. Previously we checked this with
rb_method_basic_definition_p, which avoids the method call but requires
a method lookup.
This commit replaces the previous check with BASIC_OP_UNREDEFINED_P and
a new BOP_DEFAULT. We still need to fall back to
rb_method_basic_definition_p when called on a subclasss of hash.

[Feature #17881]
Works similarly to `method_added` but for constants.
```ruby
Foo::BAR = 42 # call Foo.const_added(:FOO)
class Foo::Baz; end # call Foo.const_added(:Baz)
Foo.autoload(:Something, "path") # call Foo.const_added(:Something)
```
[0] => [0, *, a]
#=> [0] length mismatch (given 1, expected 2+) (NoMatchingPatternError)
Ignore test failures of typeprof caused by this change for now.
This reverts commit 9faef3113f.
It seemed to cause a failure on macOS Mojave, though I'm unsure how.
20190802T034503Z.fail.html.gz
This tentative revert is to check if the issue is actually caused by the
change or not.
Because hard to specify commits related to r67479 only.
So please commit again.

This reverts commit r64829. I'll prepare another temporary fix, but I'll
separately commit that to make it easier to revert that later.

not optimizing Array#& and Array#| because vm_insnhelper.c can't easily
inline it (large amount of array.c code would be needed in vm_insnhelper.c)
and the method body is a little complicated compared to Integer's ones.
So I thought only Integer#& and Integer#| have a significant impact,
and eliminating unnecessary branches would contribute to JIT's performance.
vm_insnhelper.c: ditto
tool/transform_mjit_header.rb: make sure these instructions are inlined
on JIT.
compile.c: compile vm_opt_and and vm_opt_or.
id.def: define id for them to be used in compile.c and vm*.c
vm.c: track redefinition of Integer#& and Integer#|
vm_core.h: allow detecting redefinition of & and |
test/ruby/test_jit.rb: test new insns
test/ruby/test_optimization.rb: ditto
* Optcarrot benchmark
This is a kind of experimental thing but I'm committing this since the
performance impact is significant especially on Optcarrot with JIT.
