* compile.c (iseq_peephole_optimize): should not replace the
current target INSN, not to follow the replaced dangling link in
the caller. [ruby-core:74993] [Bug #11816]

* compile.c (iseq_peephole_optimize): don't apply tailcall
optimization to send/invokesuper instructions with blockiseq.
This is a follow-up to the changes in r51903; blockiseq is now
the third operand of send/invokesuper instructions.

When you change this to true, you may need to add more tests.

Infinity cannot be written as an optimizable literal,
so it can never match a key in a CDHASH.
Avoid converting it to prevent FloatDomainError.

nil/true/false are special literals just like floats, integers,
literal strings, and symbols. Optimize when statements with
them by using a jump table, too.

The missing check for Float#=== redefinition was noticed while
working on enhancing optimized case dispatch for nil/true/false
in [ruby-core:71818] https://bugs.ruby-lang.org/issues/11769
So no, I don't normally redefine core classes like this :P
* insns.def (opt_case_dispatch): check Float#=== redefinition
* test/ruby/test_optimization.rb (test_opt_case_dispatch): new

rb_str_freeze may resize oversized buffers to save memory, so favor
it over rb_obj_freeze. This is useful because IO methods do not
prematurely shrink buffers, as they are likely to be overwritten
with full data.
* string.c (Init_String): use rb_str_freeze for String#freeze
