Bug detailed description:
---------------------------
It fails on all platforms with mesa master, but wokrs well on 10.2 branch.
glslparsertest_glsl2_16385-consecutive-chars.frag fails on i965 platforms with mesa master branch, it has same bisect commit.

Bisect shows: 04e40fd337a244ee77ef9553985e9398ff0344af is the first bad commit.

    glsl/glcpp: Treat CR+LF pair as a single newline

    The GLSL specification says that either carriage-return, line-feed, or both
    together can be used to terminate lines. Further, it says that when used
    together, the pair of terminators shall be interpreted as a single line.

    This final requirement has not been respected by glcpp up until now, (it has
    been emitting two newlines for every CR+LF pair).

    Here, we fix the lexer by using a regular expression for NEWLINE that eats
    up both "\r\n" (or even "\n\r") if possible before also considering a single
    '\n' or a single '\r' as a line terminator.

    Before this commit, the test results are as follows:

        \r:     135/143 tests pass
        \r\n:     4/143 tests pass
        \n\r:     4/143 tests pass

    After this commit, the test results are as follows:

        \r:     135/143 tests pass
        \r\n:   140/143 tests pass
        \n\r:   139/143 tests pass

    So, obviously, a dramatic improvement.
