ed69821f5b compiler-rt: Add the __atomic family of builtins 
The implementation was checked against a few files using std::atomic and
compiled using zig c++.

Closes #4887

11b50e3ad8 change the default ABI of riscv64-linux-musl 
Before, this would cause a link failure when mixing Zig and C code for
RISC-V targets.

Now, the ABIs match and Zig and C code can be mixed successfully.

I will file a follow-up issue for the ability to deal more explicitly
with ABIs.

f8cc6a1917 zig cc: fix ambiguity with -MT 
In an MSVC context, `-MT` means
"Use static run-time"
and it is a flag with no parameter.

On POSIX it means
"Specify name of main file output in depfile"
and it is "joined or separate".

The former was interfering with the latter. Now, the MT flag is required
to be specified with a `/` to disambiguate: `/MT`.

b5526d0b3b Fix multiplication overflow in hash_const_val

multiplication, instead of a 32 bit unsigned one.

8bf7cffe29 slight modification of the semantics of std.os.getenvW 
Now, this function first attempts a case-sensitive lookup.
If no match is found, and `key` is ASCII, then it attempts a
second case-insensitive lookup.

It is not planned to support full Unicode case-insensitivity
on Windows, and in fact relying on non-ASCII case-insensitive
environment variables is fundamentally problematic.

212e2354b8 stage1: make C++ switch fallthrough an error 
Make fallthrough an error when compiler supports it. This requires a new
macro that is defined with such compilers to be used as a statement, at
all fallthrough sites:

    switch (...) {
        case 0:
            ...
            ZIG_FALLTHROUGH;
        case 1:
            ...
            break;
        default:
            ...
            break;
    }

If we ever move to C++17 as minimal requirement, then the macro can be
replaced with `[[fallthrough]];` at statement sites.

d33766e6c7 Make sure that ZigTypeVector and ZigTypeArray have the same memory layout 
Throughout the stage1 code it is assumed that these have the same layout,
but that was not the case. This caused an issue on 32-bit hardware.

2e806682f4 (breaking) std.Buffer => std.ArrayListSentineled(u8, 0) 
This new name (and the fact that it is a function returning a type) will
make it more clear which use cases are better suited for ArrayList and
which are better suited for ArrayListSentineled.

Also for consistency with ArrayList,
 * `append` => `appendSlice`
 * `appendByte` => `append`

Thanks daurnimator for pointing out the confusion of std.Buffer.
