* test runner is improved to respect `error.SkipZigTest`
* start code is improved to `@setAlignStack(16)` before calling main()
* the newly passing behavior test has a workaround for the fact that
stage2 cannot yet call `std.Target.x86.featureSetHas()` at comptime.
This is blocking on comptime closures. The workaround is that there
is a new decl `@import("builtin").stage2_x86_cx16` which is a `bool`.
* Implement `@setAlignStack`. This language feature should be re-evaluated
at some point - I'll file an issue for it.
* LLVM backend: apply/remove the cold attribute and noinline attribute
where appropriate.
* LLVM backend: loads and stores are properly annotated with alignment
and volatile attributes.
* LLVM backend: allocas are properly annotated with alignment.
* Type: fix integers reporting wrong alignment for 256-bit integers and
beyond. Once you get to 16 byte aligned, there is no further
alignment for larger integers.
