* build.zig: repair the ability to link against llvm, clang, and lld
* move the zig cc arg parsing logic to stage2
- the preprocessor flag is still TODO
- the clang arg iterator code is improved to use slices instead of
raw pointers because it no longer has to deal with an extern
struct.
* clean up error printing with a `fatal` function and use log API
for messages rather than std.debug.print
* add support for more CLI options to stage2 & update usage text
- hooking up most of these new options is TODO
* clean up the way libc and libc++ are detected via command line
options. target information is used to determine if any of the libc
candidate names are chosen.
* add native library directory detection
* implement the ability to invoke clang from stage2
* introduce a build_options.have_llvm so we can comptime branch
on whether LLVM is linked in or not.

Building from Source
Note that you can download a binary of master branch or install Zig from a package manager.
Stage 1: Build Zig from C++ Source Code
Dependencies
POSIX
- cmake >= 2.8.5
- gcc >= 5.0.0 or clang >= 3.6.0
- LLVM, Clang, LLD development libraries == 10.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 3.15.3
- Microsoft Visual Studio. Supported versions:
- 2015 (version 14)
- 2017 (version 15.8)
- 2019 (version 16)
- LLVM, Clang, LLD development libraries == 10.x
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install

MacOS
brew install cmake llvm
brew outdated llvm || brew upgrade llvm
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
You will now run into this issue:
homebrew and llvm 10 packages in apt.llvm.org are broken with undefined reference to getPollyPluginInfo
or
error: unable to create target: 'Unable to find target for this triple (no targets are registered)',
in which case try -DZIG_WORKAROUND_4799=ON
Hopefully this will be fixed upstream with LLVM 10.0.1.
Windows
