2ad6ca581d Add behavior test for copying self-referential struct 
Closes #6312. In the C++ implementation this caused a stack overflow
from infinite recursion during analysis.

6bba5a39e4 Add behavior test for ptrCast on function pointer 
Closes #6280. In the C++ implementation this triggered a
compiler assertion.

4f6013bf50 add behavior test for sub-aligned field access 
The workaround in std.zig.Server remains because the C backend is not
passing the new test.

817fa3af86 std: cleanup asm usage 
After fixing some issues with inline assembly in the C backend, the std
cleanups have the side effect of making these functions compatible with
the backend, allowing it to be used on linux without linking libc.

Allow zero-sized fields in extern structs (#16404) 
This change allows the following types to appear in extern structs:
* Zero-bit integers
* void
* zero-sized structs and packed structs
* enums with zero-bit backing integers
* arrays of any length with zero-size elements

8c367ef99a codegen: fix access to byte-aligned nested packed struct elems 
When acessing a packed struct member via a byte aligned ptr (from the optimisation in Sema.structFieldPtrByIndex())
the codegen must apply the parent ptr packed_offset in addition to the field offset itself.

c80609dfec Sema: don't reorder tuple fields

e66190025f frontend: make fn calls byval; fix false positive isNonErr 
This commit does two things which seem unrelated at first, but,
together, solve a miscompilation, and potentially slightly speed up
compiler perf, at the expense of making #2765 trickier to implement in
the future.

Sema: avoid returning a false positive for whether an inferred error set
is comptime-known to be empty.

AstGen: mark function calls as not being interested in a result
location. This prevents the test case "ret_ptr doesn't cause own
inferred error set to be resolved" from being regressed. If we want to
accept and implement #2765 in the future, it will require solving this
problem a different way, but the principle of YAGNI tells us to go ahead
with this change.

Old ZIR looks like this:

  %97 = ret_ptr()
  %101 = store_node(%97, %100)
  %102 = load(%97)
  %103 = ret_is_non_err(%102)

New ZIR looks like this:

  %97 = ret_type()
  %101 = as_node(%97, %100)
  %102 = ret_is_non_err(%101)

3c08fe931a make @typeInfo not return private decls 
fixes #10731
Thanks @nektro for previous work in #14878

This change creates a small breaking change:
It removes the `is_pub` field of a decl in `@typeInfo`

619140c0d2 wasm: correctly intcast signed integers 
When a signed integer's bitsize is not 32 or 64, but the given
bitsize and wanted bitsize are either both represented by Wasm's i32
or i64, we must either sign extend or wrap the integer.

5b594139d9 Sema: copy pointer alignment to union field pointers 
This implements the semantics as discussed in today's compiler meeting,
where the alignment of pointers to fields of default-layout unions
cannot exceed the field's alignment.

4620972d08 Sema: preserve extern struct field alignment 
In

    extern struct { x: u32, y: u16 }

we actually know that y's alignment is `@alignOf(u32)`, and not just
`@alignOf(u16)`.
