ca0d54d51b Enhance readability of error messages for GLSL 
Specifically, make GLSL link error messages more specific and output
only information relevant to the error.

Also change type printing to more closely reflect GLSL syntax. This
is the default for link error messages, but must me enabled with the
new option --enhanced-msgs for compilation error messages.

Also with --enhanced-msgs, only emit one error message per source
line.

fix incorrect error when multiple compilation units don't declare layouts (#2238) 
when using multiple compilation units, input/output layouts don't need
to be declared in every unit.

ead8622484 Non-functional. Rationalizations enabling future generalizations: 
- Use much simpler method to update implicit array sizes.
  The previous overly complicated method was error prone.
- Rationalize all use of unsized arrays.
- Combine decorations when generating SPIR-V, to simplify
  adding extensions.

1c3ab274b1 Test Results Only: Include size in implicitly sized arrays (change to unsized). 
This effects 60 tests, in a trivial way, but is critical to factor out this
noise from future planned changes.

71c100d7c0 GLSL output: Removed fixed-size buffer; fixes #769. 
Makes some white-space differences in most output, plus a few cases
where more could have been put out but was cut short by the previous
fix-sized buffer.

4b6ce415ef GLSL Linker: Track entry point across compilation units. 
This wasn't needed until the recent generalization of "main" to "entry point",
so makes some HLSL-specific code be generic now, for GLSL functional correctness.

d82c906378 Vulkan: Finish semantics for what creates spec-const-semantics. 
Note: This required adding a new test mode to see the AST for vulkan tests.
This also required reworking some deeper parts of type creation, regarding
when storage qualification and constness is deduced bottom-up or dictated
top-down.

b5c046e58b Front-end: Fix missing tessellation shader built-in qualifiers. 
The gl_in array has a special path due to context-specific
gl_MaxPatchVertices, making the code out of order for tagging built-ins.
This commit moves the tagging to the correct location.
This also fixes issue #80.

f2d042a1fe Non-functional, infrastructure: Be more explicit about "implicit array sizes", improving the infrastructure for handling them. Also fix some output that was too big for its buffer.

5053a39578 Fix slight inconsistencies in which qualifiers are inherited into block members: 
- don't inherit 'binding'
 - always set the member storage qualifier, not just when the shader explicitly set it
 - don't include in/out members as objects that are resized by geometry/primitive layout specifiers
As a side effect, this makes built-in redeclarations (like gl_ClipDistance) require in/out.
