Add a keyword argument to to_native() to operate on a copy so that we
can call it multiple times instead of modifying the original compiler
args while iterating.
This is used in the unit test, and might be used in Meson at some
point too.
- For optimization=s add /O1: Use Maximum Optimization (Favor Size),
and remove /Os as it's implied by /O1.
- Because we add /O1, this implies /Gy, i.e. Function-Level Linking, so
unused code can be omitted.
- Add /Gw: Optimize Global Data, so unused data can be omitted.
With buildtype=minsize on x86 this reduces the size of a statically
linked Vala compiler binary from 5 MB down to just 1.87 MB.
This means that we will take into account all the flags set in the
cross file when fetching the list of library dirs, which means we
won't incorrectly look for 64-bit libraries when building for 32-bit.

The fallback to compilers.base_options was done after optname is changed
to have subproject prefix. Simplify the code by looping over all
dictionaries and only keep user_options separate because that one is
special.
Implement a string converter in our WrapMode enum so that argparse will
only print the names in the doc instead of WrapMode.<name>.
This changes --help command from printing:
--wrap-mode {WrapMode.default,WrapMode.nofallback,WrapMode.nodownload,WrapMode.forcefallback}
to:
--wrap-mode {default,nofallback,nodownload,forcefallback}
Fixes issue #4067
pkg-config and pkgconf treat additional search paths in
PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR differently when
PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 is set.
pkg-config always outputs -L flags for the additional paths first, and
pkgconf always outputs -L flags for the default paths first.
To account for this inconsistency, we now sort the library paths into
two separate sets: system (default) and prefix (additional) paths. We
can do this because we always query pkg-config twice: once with
PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 set and once without it.
Then, we ensure that the prefix paths are searched before the system
paths.

* GCC 4.8 and Clang 3.2, 3.3, 3.4 only understand
`-std={c,gnu}++1y` for enabling C++14 dialects.
GCC 4.8 is especially important as it is the basis
of RHEL/CentOS 7.
These weren't caught by the CI because we have pkg-config on it, and
these were testing non-pkg-config codepaths. The unity build on macOS
now doesn't have pkg-config to ensure that the codepath is tested.
