Bug detailed description:
-----------------------------
It fails on Ironlake/Sandybridge/Ivybridge/Haswell/Baytrail with mesa master branch. It doesn't happen on 10.0 branch.
(GLES20)GL_build_DuplicateVersion1_V100_frag.test also fails with same bisect commit.

Bisect shows: 3e0e9e3bf9e597eb74b06381b3418c958be4d452 is the first bad commit.

    glcpp: Check version_resolved in the proper place.

    The check was in the wrong place, such that if a shader incorrectly put
    a preprocessor token before the #version declaration, the version would
    be resolved twice, leading to a segmentation fault when attempting to
    redefine the __VERSION__ macro.

     #extension GL_ARB_sample_shading: require
     #version 130
     void main() {}

    Also, rename glcpp_parser_resolve_version to
                 glcpp_parser_resolve_implicit_version to avoid confusion.
