implement anon struct literal syntax

Browse Source 
This implements stage1 parser support for anonymous struct literal
syntax (see #685), as well as semantic analysis support for anonymous
struct literals and anonymous list literals (see #208). The semantic
analysis works when there is a type coercion in the result location;
inferring the struct type based on the values in the literal is not
implemented yet. Also remaining to do is zig fmt support for this new
syntax and documentation updates.
