It used to be that usingnamespace was only allowed at top level. This
made it OK to put the state inside the AST node data structure. However,
now usingnamespace can occur inside any aggregate data structure, and
therefore the state must be in the TopLevelDeclaration rather than in
the AST node.
There were two other problems with the usingnamespace implementation:
* It was passing the wrong destination ScopeDecl, so it could cause an
incorrect error such as "import of file outside package path".
* When doing `usingnamespace` on a file that already had
`pub usingnamespace` in it would "steal" the usingnamespace, causing
incorrect "use of undeclared identifier" errors in the target file.

Previously, global assembly was parsed expecting it to have
the template syntax. However global assembly has no inputs,
outputs, or clobbers, and thus does not have template syntax.
This is now fixed.
This commit also adds a compile error for using volatile
on global assembly, since it is meaningless.

This commit contains everything from the copy-elision-2
branch that does not have to do with copy elision directly,
but is generally useful for master branch.
* All const values know their parents, when applicable, not
just structs and unions.
* Null pointers in const values are represented explicitly,
rather than as a HardCodedAddr value of 0.
* Rename "maybe" to "optional" in various code locations.
* Separate DeclVarSrc and DeclVarGen
* Separate PtrCastSrc and PtrCastGen
* Separate CmpxchgSrc and CmpxchgGen
* Represent optional error set as an integer, using the 0 value.
In a const value, it uses nullptr.
* Introduce type_has_one_possible_value and use it where applicable.
* Fix debug builds not setting memory to 0xaa when storing
undefined.
* Separate the type of a variable from the const value of a variable.
* Use copy_const_val where appropriate.
* Rearrange structs to pack data more efficiently.
* Move test/cases/* to test/behavior/*
* Use `std.debug.assertOrPanic` in behavior tests instead of
`std.debug.assert`.
* Fix outdated slice syntax in docs.
See #770
Currently it does not have any different behavior than `*`
but it is now recommended to use `[*]` for unknown length
pointers to be future-proof.
Instead of [ * ] being separate tokens as the proposal
suggested, this commit implements `[*]` as a single token.
See #770

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
start using zig-fmt-pointer-reform branch build of zig fmt
to fix code to use the new syntax
all of test/cases/* are processed, but there are more left
to be done - all the std lib used by the behavior tests
* instead of `async(allocator) call()`, now it is
`async<allocator> call()`.
* Fixes syntax ambiguity when leaving off the allocator
* Fixes parse failure when call is a field access
This sets a precedent for using `<` to pass arguments
to a keyword. This will affect `enum`, `union`, and
`fn` (see #661)
