Some layout qualifiers must not be on an object and had a TBD for testing
them: early_fragment_tests, cw/ccw, points, point_mode, and
fractional_even_spacing/fractional_odd_spacing/equal_spacing.

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.

'invocations' was using 0 as the "shader never set" flag and as the
default. Formalize this and explicit set to 1 and link time.

To do this, more generally use a named -1 as a not set value.

glslang: Formally track all built-in variables, right from the beginning, to enable avoiding all textual compares at any subsequent stage in the stack.  (To be used in future check ins.)

glslang AST output: include global vs. temp (local) in the printed output.  This only effects test results, but a future check-in is going to fix some globals.
