glcpp: error on multiple #else/#elif directives
The preprocessor currently accepts multiple else/elif-groups
per if-section. The GLSL-preprocessor is defined by the C++
specification, which defines the following parse-rule:
if-section:
if-group elif-groups(opt) else-group(opt) endif-line
This clearly only allows a single else-group, that has to come
after any elif-groups.
So let's modify the code to follow the specification. Add test
to prevent regressions.
