compilers/d: Add b_ndebug support D lang compilers have an option -release (or similar) which turns off asserts, contracts, and other runtime type checking. This patch wires that up to the b_ndebug flag. Fixes #7082

project('preserve subdir', 'c')
gprog = find_program('genprog.py')
gen = generator(gprog, \
output : ['@BASENAME@.c', '@BASENAME@.h'],
arguments : ['--searchdir=@CURRENT_SOURCE_DIR@', '--outdir=@BUILD_DIR@', '@INPUT@'])
generated = gen.process('base.inp', 'com/mesonbuild/subbie.inp',
preserve_path_from : meson.current_source_dir())
fix crash in generator.process() with an invalid preserve_path_from This code cleverly tried to use a fancy new pathlib.Path method to get the os.path.commonpath of two paths and check whether one is inside the other. It failed pretty badly, because of a hidden secret of pathlib: it is designed to throw random exceptions at all times (except when building os.PathLike interfaces) instead of performing useful work. Return to `os.path`. In particular, before this change, we wanted to check if files are NOT in a subpath of `preserve_path_from`, and raise a meson "ERROR: xxx" in such a case. However, the code to check for it would raise a python ValueError if that was the case, so we never got to the properly formatted error.
