This reverts commit 594075a2f0.
Reason for revert: This is not a complete solution. It does not cover assignment of variables of the same struct type, but of different access types. For example:
```
[[block]] struct S{ i : 32; };
var<storage> gr : [[access(read)]] S;
var<storage> gw : [[access(write)]] S;
fn f() {
var a : S;
a = gr;
gw = a;
}
```
With my CL, we currently generate invalid assignments because the new types of 'S' for 'gr' and 'gw' are now all different types. We would need to generate functions to assign between them.
In the end, we will drop this strategy, and instead, Dawn will be modified to not rely on names.

* Handles the address-of and indirection operators.
* No longer does any implicit loads of pointer types.
* Storage class validation is still TODO (crbug.com/tint/809)

- Add optional second argument test/test-all.sh to specify a directory
look for input files.
- BUILD.gn: Add dependency from //test:tint_unittests_main to

This makes the .cc files match the header file name, which allows for
the text editor "header flip" feature to actually work. The reason these
files were named this way was because GN doesn't allow name conflicts in
the same source set, despite the files being in different directories.
This change splits the files into different source sets. To do so, we
use GN templates, which also reduces duplication in each target
definition.

There is still no way to spell this out in WGSL, but this adds support
for VariableDecls with an ast::Variable that has nullptr type. In this

which is stored in semantic::Variable.
Added tests for resolving inferred types from constructor, arithmetic,
and call expressions.
