Exclude sanitizer flags from LLVM JIT bitcode generation
The meson build passes c_args verbatim to the clang command that emits the JIT bitcode. Under -fsanitize=address the instrumentation ends up in the bitcode and breaks the JIT: any JIT-compiled query crashes the backend with SIGILL. The autoconf build is unaffected, as it builds BITCODE_CFLAGS from a whitelist that never includes CFLAGS. Filter sanitizer flags out of c_args during bitcode generation.

Filter sanitizer flags from the LLVM JIT bitcode in the autoconf build
Sanitizer instrumentation in the JIT bitcode corrupts the JIT code generator: any JIT-compiled query crashes the backend with SIGILL. The autoconf build rebuilds BITCODE_CFLAGS from a whitelist and does not normally let sanitizer flags in, but filter them out of BITCODE_CFLAGS/BITCODE_CXXFLAGS explicitly to also cover flags supplied through those variables, and warn when any are stripped. Also add -g to the bitcode flags under --enable-debug so the JIT bitcode carries debug info; sanitizer flags stay excluded, so this is safe. Author: Henson Choi <assam258@gmail.com>

Add jit regression test to exercise the LLVM JIT path
The default is jit = off, so the regular regression suite no longer exercises the LLVM JIT. Add a small test that turns jit on and sets jit_above_cost to zero, so that even a trivial query enables JIT and initializes the JIT provider. On a working installation it returns the expected result. Author: Henson Choi <assam258@gmail.com>
