    • compiler: fix bug in handling of unordered set during exporting · b94b6cc0 
          
    In CL 183850 a change was made to combine tracking/discovery of
    exported types and imported packages during export data generation. As
    a result of this refactoring a bug was introduced: the new code can
    potentially insert items into the exports set (an unordered_set) while
    iterating through the same set, which is illegal according to the spec
    for std::unordered_set.
    
    This patch fixes the problem by changing the type discovery phase to
    iterate through a separate list of sorted exports, as opposed to
    iterating through the main unordered set.  Also included is a change
    to fix the code that looks for variables that are referenced from
    inlined routine bodies (this code wasn't scanning all of the function
    that it needed to scan).
    
    New test case for this problem in CL 186697.
    
    Updates golang/go#33020.

    • -Wmissing-attributes: check that we avoid duplicates and false positives · dea78431 
      The initial patch for PR 81824 fixed various possibilities of
-Wmissing-attributes reporting duplicates and false positives.  The
test that avoided them was a little obscure, though, so this patch
rewrites it into a more self-evident form.

The patch also adds a testcase that already passed, but that
explicitly covers some of the possibilities of reporting duplicates
and false positives that preexisting tests did not cover.

    • Simplify range location creation in C++ parser. · 6eaf3f9e 
      Many places in the parser follow the same pattern of capturing the location
of the last lexed token, either before or after lexing it, and then using
that as the end of a location range; this can be simplified by passing the
lexer to make_location and grabbing the token location there.
