Ian Lance Taylor c2f879e1fe compiler: make escape analysis work with imported inlineable functions 
The escape analysis was written before we import inlineable
    function bodies, and in some places it skipped functions that are
    not in the local package. Now that there are imported function
    bodies, make the escape analysis work with them.
    
    Note that it is necessary for the escape analysis to run on
    imported function bodies, even if they are already tagged. The
    tags only have the information of the parameters (receiver,
    results), but not the internal nodes, e.g. local variables. We
    still need to do the analysis to get all the information. (In the
    future maybe we could export/import escape info for internal
    nodes also, then we don't need to redo the analysis.)
    
    Also add assertions to ensure that if we analyze the same
    function in multiple places, they'd better agree with each other.

Jonathan Wakely 39d1184ba8 PR other/90695 reduce testcase to remove library dependency 
This reproduces the original ICE fixed by r178857 (tested at r178852 and
r178860), without depending on a libstdc++ header that keeps changing.

The number of errors differs between C++14 and C++17 modes, so the fixed
test uses dg-excess-errors to match any number of them. The precise
errors aren't what's being tested for here anyway, the point of the test
is to verify the ICE in PR 50391 is fixed.

Ian Lance Taylor ab658f56a5 compiler: do simple deadcode elimination 
Normally the backend will do deadcode elimination and this is
    sufficient. However, the escape analysis operates on the AST that
    may have deadcode, and may cause things to escape that otherwise
    do not.
    
    This CL adds a simple deadcode elimination, run before the escape
    analysis.
