ANGLE_instanced_arrays extension addendum for index validation
Add proposal for WEBGL_draw_elements_no_range_check

The goal of the extension is to eliminate one common source of WebGL CPU
overhead by removing drawElements index validation.

The extension changes the behavior of drawElements as opposed to
introducing a new call or a toggleable flag to make it possible to get
rid of index buffer copies in CPU memory entirely after the extension
has been enabled.

Remove precision qualifiers from booleans in constructor tests

Use default precision qualifiers for float and int instead. Booleans or
literals do not have precision qualifiers.
Add tests for a literal and booleans with a precision qualifier

According to GLSL spec, boolean variables and literals do not
have a precision qualifier, so compilation should fail in these cases.
