fallback to opt_send_without_block because of vm_method_cfunc_is.

Actually opt_eq becomes slower by this. Maybe it's indeed using
opt_send_without_block, but I'll approach that one in another commit.
These days I don't use `make benchmark`. The YAML files should be
executable with bare `benchmark-driver` CLI without passing
`RUBYOPT=-Ibenchmark/lib`.

But so far no idea why it's happening. Until I get direct ssh access to
debug the details, let me skip this as it's essentially not ruby's fault.
A prerequisite to fix https://bugs.ruby-lang.org/issues/15589 with JIT.
This commit alone doesn't make a significant difference yet, but I thought
this commit should be committed independently.
This method override was discussed in [Misc #16961].
This problem exists because Marshal.load calls Date.allocate, which
uses a SimpleDateData. There doesn't seem to be any support for
taking an existing Date instance and converting it from SimpleDateData
to ComplexDateData. Work around this issue by making Date.allocate
use a ComplexDateData. This causes problems in Date#initialize,
so remove the Date#initialize method (keeping the date_initialize
function, used internally for Date.civil). Alias Date.new to
Date.civil, since they do the same thing.

Formerly, branch coverage measurement counters are generated for each
compilation traverse of the AST. However, ensure clause node is
traversed twice; one is for normal-exit case (the resulted bytecode is
embedded in its outer scope), and the other is for exceptional case (the
resulted bytecode is used in catch table). Two branch coverage counters
are generated for the two cases, but it is not desired.
This changeset revamps the internal representation of branch coverage
measurement. Branch coverage counters are generated only at the first
visit of a branch node. Visiting the same node reuses the
already-generated counter, so double counting is avoided.
Previously, these were not implemented, and Object#== and #eql?
were used. This tries to check the proc internals to make sure
that procs created from separate blocks are treated as not equal,
but procs created from the same block are treated as equal, even
when the lazy proc allocation optimization is used.
Implements [Feature #14267]
instead of `@root.encoding`.
And fallback to ASCII-8BIT when filesystem encoding is US-ASCII.
When `@root.encoding` is not compatible filesystem encoding,
`Encoding::CompatibilityError` raised at `webrick/httpservlet/filehandler.rb:341`.
So `DocumentRoot` must be compatible with filesystem encoding.

`prevent_directory_traversal` treats `path_info` as filesystem encoding.
So path_info should be filesystem encoding in request URL.
On some environments, fallback to ASCII-8BIT when EncodingError.
