c55fc39acb [ast] Unify the access control types.
This CL merges the StorageAccess enum with the AccessControl enum. The

4dd5665502 Add tests for all reachable parser errors
These are _mostly_ covered in the over various test files, but unlike those, these new tests always parse from the root translation unit.

These new tests also use a new testing class which may be extended to verify error output for different error styles (verbosity, colors, etc).

488d7a9346 [spirv-writer] Fix emission of OpExecutionMode
All of the OpEntryPoint declarations must come before OpExecutionMode.
Currently if you have multiple fragment shaders we'll interleave the
OpEntryPoint and OpExeutionMode which will fail to validate.

b8d90ead93 Move visibility=hidden directive.
This CL moves the visibility=hidden directive from the top level applied
flags to libtint specifically. This fixes up an issue between
SPIRV-Tools and the sample app when using std::rfind which ends up with
different visibility.

b5e5b804c3 Reduce duplication of type format strings.
This CL makes the AST type format name match the WGSL name so the
overloaded operator<< can be used in the WGSL writer. This removes a
bunch of duplication of WGSL type format name strings.

1a9a2dd07d Add Inspector class
This class is used to examine a module and get information about its
contents. This is the getting side of shader of reflection. Future
work will add transforms that perform the setting side of reflection.

In addition to the basic class and infrastructure, this CL adds a
GetEntryPoints() function demonstrate it works. More functionality
will be added in later CLs.
