Merge branch 'ab/pcre-jit-fixes'
A few simplification and bugfixes to PCRE interface.
* ab/pcre-jit-fixes:
grep: under --debug, show whether PCRE JIT is enabled
grep: do not enter PCRE2_UTF mode on fixed matching
grep: stess test PCRE v2 on invalid UTF-8 data
grep: create a "is_fixed" member in "grep_pat"
grep: consistently use "p->fixed" in compile_regexp()
grep: stop using a custom JIT stack with PCRE v1
grep: stop "using" a custom JIT stack with PCRE v2
grep: remove overly paranoid BUG(...) code
grep: use PCRE v2 for optimized fixed-string search
grep: remove the kwset optimization
grep: drop support for \0 in --fixed-strings <pattern>
grep: make the behavior for NUL-byte in patterns sane
grep tests: move binary pattern tests into their own file
grep tests: move "grep binary" alongside the rest
grep: inline the return value of a function call used only once
t4210: skip more command-line encoding tests on MinGW
grep: don't use PCRE2?_UTF8 with "log --encoding=<non-utf8>"
log tests: test regex backends in "--encode=<enc>" tests
