84fdeb47a3 compiler-rt: fix usage of builtin 
In this branch std.builtin and `@import("builtin")` are rearranged, fix
a trivial compile error due to the conflict with master.

597082adf4 Merge remote-tracking branch 'origin/master' into stage2-whole-file-astgen 
Conflicts:
 * build.zig
 * src/Compilation.zig
 * src/codegen/spirv/spec.zig
 * src/link/SpirV.zig
 * test/stage2/darwin.zig
   - this one might be problematic; start.zig looks for `main` in the
     root source file, not `_main`. Not sure why there is an underscore
     there in master branch.

5185b5619a compiler-rt: Fix signedness mismatch in f128 mul impl 
The `1 - shift` expression was computed using small unsigned types and
then casted to i32, producing either an underflow error or an incorrect
result.

Reported by `@notviri` in #8733

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.

4bf093f1a0 compiler-rt: Better selection of __clzsi implementation 
To be honest all this detection logic is starting to become a real PITA,
the ARM32 version can be possibly removed as the generic version
optimizes pretty well...

518168edb2 compiler-rt: Avoid exposing atomic builtins when not supported 
Let's a void any kind of compilation/LLVM errors for niche targets such
as AVR/MSP430 or ARM v6m. By not exporting any atomic builtin anymore
the user is free to provide their own implementation (that disable the
IRQs) or to provide the --single-threaded switch and forget about this.

a0b73c9f02 compiler-rt: Separate max size allowed for load/store and CAS 
The v6m ISA has no way to express a CAS loop natively without turning
off the interrupts or using the kernel cmpxchg harness.

On such a platform the user has to provide a few __sync_* builtins to
satisfy the linker.
