The compiler runs on Windows (and has seeds for macOS)

Browse source 
Windows: the compiler made from bootstrap/windows-x86_64.ll runs under Wine, compiles itself to the same IR, builds an
exe of itself, and every test program passes through it. It needed: Windows-sized unsigned long for libclang's unsaved
file, no 'cross' when Windows builds for Windows, --target passed to libclang (libclang.dll assumes MSVC), the MinGW
triple always in the IR, FINCH_LDFLAGS, .exe names and FINCH_LLVM_INCLUDE in bootstrap/build.sh, winseed.sh/winbuild.sh.
macOS: seeds for arm64 and x86-64 made with the 11.3 SDK; IR is accepted by clang, nothing has run on a Mac yet.
CI gets a windows and a macos job. UNTESTED on real Windows/macOS runners.

# The compiler is written in Finch. It is built from bootstrap/<system>.ll, its own LLVM IR (see bootstrap/README.md),
# then from itself. Linux x86-64 and ARM64 have seeds; macOS and Windows machines can't build the compiler yet
# (programs for them are built from Linux with --target, and tested here under Wine and qemu).
# then from itself. Seeds: Linux x86-64 and ARM64 (tested here), Windows x86-64 (tested under Wine, and here),
# macOS ARM64 and x86-64 (made with Apple's headers; only checked as IR until the macos job below passes).
