regexec: use pcre as our fallback/builtin regex Use PCRE 8.42 as the builtin regex implementation, using its POSIX compatibility layer. PCRE uses ASCII by default and the users locale will not influence its behavior, so its `regcomp` implementation is similar to `regcomp_l` with a C locale.

Some are compile-time only, some are run-time only, and some are both. Most of the compile-time options are saved with the compiled regex so that they can be inspected during studying (and therefore JIT compiling). Note that pcre_study() has its own set of options. Originally, all the options defined here used distinct bits. However, almost all the bits in a 32-bit word are now used, so in order to conserve them, option bits that were previously only recognized at matching time (i.e. by pcre_exec() or pcre_dfa_exec()) may also be used for compile-time options that affect only compiling and are not relevant for studying or JIT compiling. Some options for pcre_compile() change its behaviour but do not affect the behaviour of the execution functions. Other options are passed through to the execution functions and affect their behaviour, with or without affecting the behaviour of pcre_compile(). Options that can be passed to pcre_compile() are tagged Cx below, with these variants: C1 Affects compile only C2 Does not affect compile; affects exec, dfa_exec C3 Affects compile, exec, dfa_exec C4 Affects compile, exec, dfa_exec, study C5 Affects compile, exec, study Options that can be set for pcre_exec() and/or pcre_dfa_exec() are flagged with E and D, respectively. They take precedence over C3, C4, and C5 settings passed from pcre_compile().
