Instead of creating Module.Decl objects, directly create InternPool
pointer values using the anon_decl Addr encoding.
The LLVM backend needed code to notice the alignment of the pointer and
lower accordingly. The other backends likely need a similar change.
This completes the migration from spv.ptrType to self.ptrType.
Unfortunately this requires us to pass a list of types to
constructStruct, which also requires some extra allocations
here and there.
This removes the strategy where union with different active
fields would be generated, and instead simply pointer casts
the active field type where required. This also allows removing
spv.ptrType and using self.ptrType instead, and allows caching
all union types (because there is only the canonical one).
This struct is used to configure the load, such as to make
it volatile. Previously this was done using a single bool, but
this struct makes it shorter to write non-volatile loads (the
usual) and more clear whats going on when a volatile load is
required.
To support self-referential pointers, in the future we will
need to pass the Zig type to any pointer that is created. This
lays some ground work for that by replacing most uses of
spv.ptrType with a new ptrType function that also accepts the
Zig type. This function's contents will soon be replaced by
a version that also supports self-referential pointers.
Also fixed some bugs regarding the use of direct/indirect.
The Khronos SPIRV-LLVM translator does not parse OpSource correctly. This
was causing tests to fail and other mysterious issues.
These are resolved by only generating a single OpSource instruction for now,
which does not have the source file locations also.

The previous code incorrectly added `sub_path` twice.
Also for the compilation unit, it was passing empty string to realpath,
resulting in the error handling codepath being used.

Finish the work started in 4c4fb839972f66f55aa44fc0aca5f80b0608c731.
Now the compiler compiles again.
Wire up dependency tree fetching code in the CLI for `zig build`.
Everything is hooked up except for `createDependenciesModule` is not yet
implemented.
for wasm, as a heuritic, only enable truncation for values smaller than 32bits.
-> the bug is no longer triggered in most use cases (or at least the test suite...)
as for powerpc, adding a redundant `and mask` produces working code.
