ea499203fe macho: incrementally write dyld_private and stub_helper atoms 
By incrementally I mean using the incremental linker machinery
and concepts. Currently, lots of repetition but already highlighted
a potential problem with resolving relocations for symbols that
weren't seen yet but wanting to write the atom to file (before
seeing the relevant atoms).

d63d8ae1c0 macho: create __stub_helper preamble atom 
with relocations to `dyld_private` and `__dyld_stub_binder` symbols
making the routine properly dynamic (i.e., making it possible to call
the routine before VM allocation takes place).

2d10c52b3c macho: create an explicit symbol and atom for dyld entry in __data 
This way, we will be able to refer to that atom dynamically via
relocations rather than requiring hardcoded addressing upfront.

52f9b283a7 macho: fix writeSymbolTable() function 
After merging `populateMetadata` with `populateMissingMetadata`,
it is imperative we clear the number of symbols in `writeSymbolTable`.
However, this is hopefully just a temp measure until the convergence
of incremental with traditional is complete.

7e07df06a4 ComptimeStringMap: expose kvs array in returned struct 
Allows for iterating over the kvs when constructing with a list literal instead of having to create a separate array to pass into ComptimeStringMap in order to maintain access to the values.

For example when making a set, before in order to loop over the kvs you'd have to do something like:

    const MyKV = struct { @"0": []const u8 };
    const kvs: []const MyKV = &[_]MyKV{ .{ @"0" = "foo"}, .{ @"0" = "bar" } };
    const map = ComptimeStringMap(void, kvs);
    for (kvs) |kv| {}

whereas now it's possible to do:

    const map = ComptimeStringMap(void, .{ .{"foo"}, .{"bar"} });
    for (map.kvs) |kv| {}

55c6a784a5 stage2 frontend improvements - @ptrCast and optionals 
* AstGen: use coerced_ty ResultLoc on array types and rely on Sema
   doing type coercion, to reduce the size of the ZIR for these
   instructions.

 * Sema: implement `@ptrCast`.

 * Sema: implement coercion from `T` to `?T` with an intermediate
   coercion rather than equality check.

fc55814faa compiler-rt: do not depend on usingnamespace 
The idea is to depend on this language feature as little as possible
with the hopes that it can be adjusted to be less of an anti-pattern.
This also helps self-hosted, which does not yet implement
`usingnamespace`, get closer to being able to build compiler-rt.
