fix redefinition optimization for -"literal string" (UMinus)
Unfortunately this enlarges insns.def by yet another
instruction. However, it is much prettier than opt_str_freeze
in use, and maybe we can avoid having so many instructions in
the future.
[ruby-core:80368]
* insns.def (DEFINE_INSN): new instruction: opt_str_uminus (maybe temporary)
* compile.c (iseq_compile_each0): split instructions
* test/ruby/test_optimization.rb (test_string_uminus): new test
* vm.c (vm_init_redefined_flag): set redefinintion flag for uminus
* vm_core.h (enum ruby_basic_operators): add BOP_UMINUS
