llvm: Also apply the nobuiltin attribute for the no_builtin module option. 
From `zig build-exe --help`:

  -fno-builtin              Disable implicit builtin knowledge of functions

It seems entirely reasonable and even expected that this option should imply
both no-builtins on functions (which disables transformation of recognized code
patterns to libcalls) and nobuiltin on call sites (which disables transformation
of libcalls to intrinsics). We now match Clang's behavior for -fno-builtin.

In both cases, we're painting with a fairly broad brush by applying this to an
entire module, but it's better than nothing. #21833 proposes a more fine-grained
way to apply nobuiltin.

b57819118d
Compilation: Move no_builtin to Package.Module. 
This option, by its very nature, needs to be attached to a module. If it isn't,
the code in a module could break at random when compiled into an application
that doesn't have this option set.

After this change, skip_linker_dependencies no longer implies no_builtin in the
LLVM backend.

bd8ef0036d llvm: Use no-builtins attribute instead of nobuiltin. 
The former prevents recognizing code patterns and turning them into libcalls,
which is what we want for compiler-rt. The latter is meant to be used on call
sites to prevent them from being turned into intrinsics.

6b2c8fc688 zig.h: Improve portability of zig_*_windows_teb() helpers. 
* Make it work for thumb and aarch64.
* Clean up std.os.windows.teb() a bit.

I also updated stage1/zig.h since the changes are backwards-compatible and are
necessary due to the std.os.windows changes that call the newly-added functions.

814a41b48f link.Coff: Pass -lldmingw to LLD earlier and regardless of -lc. 
The -lldmingw option affects a lot of logic throughout LLD. We need to pass it
for *-windows-gnu even when we're not actually linking MinGW since we're still
using the MinGW ABI with all that that entails. (One particular problem we would
run into is missing handling of stdcall-decorated symbols for 32-bit x86.) Also,
various other LLD options are sensitive to this option, so it's best to pass it
as early as possible.

Closes #11817.

std.Target: Replace isARM() with isArmOrThumb() and rename it to isArm(). 
The old isARM() function was a portability trap. With the name it had, it seemed
like the obviously correct function to use, but it didn't include Thumb. In the
vast majority of cases where someone wants to ask "is the target Arm?", Thumb
*should* be included.

There are exactly 3 cases in the codebase where we do actually need to exclude
Thumb, although one of those is in Aro and mirrors a check in Clang that is
itself likely a bug. These rare cases can just add an extra isThumb() check.
