Comment out non-x86_64 architectures for now in codegen.zig, because they all have compile errors for their codepaths anyway, and it was bloating the compilation speed and memory usage when stage1 tried to build self-hosted. Here's the panic message: "Backend architectures that don't have good support yet are commented out, to improve compilation performance. If you are interested in one of these other backends feel free to uncomment them. Eventually these will be completed, but stage1 is slow and a memory hog." This is a workaround to lower the time it takes to build self-hosted with stage1 as well as use less memory. It should fix the CI. Additionally: * Add `single_mut_pointer` support to `Type` * Trivial implementation of stack allocation in codegen.zig. It does not deal with freeing yet, and it's missing the stack pointer adjustment prologue. * Add the `alloc` IR instruction and semantic analysis for `alloc` ZIR instruction.

Building from Source
Note that you can download a binary of master branch.
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brew outdated llvm || brew upgrade llvm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
