d44486b274 std: Add libssp implementation for GNU/Windows targets 
Unlike glibc and musl, MinGW provides no libssp symbols leading to
countless compile errors if FORTIFY_SOURCE is defined.

Add a (incomplete) implementation of libssp written in Zig so that
linking succeeds.

Closes #6492

f78380b936 stage1: Don't ask LLVM to emit misaligned memcpy 
Pay close attention to the RHS type alignment when rendering an
assignment op as it may differ from the LHS pointer one.

This problem was noticed when debugging a CI failure in #6648: due to
sheer luck the misalignment caused a segfault on macos that was also
reproduced locally.

I tried to write a small test case but it turned out to be a daunting
task as I couldn't manage to trigger the problem consistently (and stop
the optimizer from simplifying everything). Patches welcome.

* remove GetModuleHandleA from kernel32.zig. use of A functions
   considered harmful.
 * make it a compile error to expose WinMain instead of wWinMain. same
   thing.
 * start code declares wWinMainCRTStartup instead of WinMainCRTStartup
   when it has the choice.

c0e9d3fb86 Classify .tbd files as shared libraries 
On macOS, a .tbd ("text-based dylib definition") file is a shared library
stub, allowing symbols to be defined only once for all the architectures
the library was compiled for.

.tbd files can be linked like .dylib files.
