    This patch introduces the Package_alias class which is a
    finer representation of the different between a package and the
    aliases it is imported under.  Each alias keeps track of the location
    of its import statement and how many times that alias has been used.
    This allows the gofrontend to report when a specific import has not
    been used even if a symbol from the package has been used by another
    import.
    
    Fixes golang/go#12326.

Analyze only those bbs which are outside the region for uses which might be
defined inside the region. This is intended to improve the compile time. This
algorithm may be further improved by only looking at the successors of region as
these regions are sese. Added FIXMEs to make this improvement in future.

Passes regtest and bootstrap on x86_64.

        * graphite-sese-to-poly.c (build_loop_iteration_domains): Only loops
        which are in this region are passed so gcc_assert and remove redundant
        computation.
        * sese.c (sese_build_liveouts): Pass only those bbs which are not in region.
        (sese_bad_liveouts_use): Only BBs which are not in region are passed so
        gcc_assert on that and remove unnecessary computation.
        (sese_build_liveouts_use): Same.

1. Move declarations near the assignment/usage.
2. Assign type to members which were void*.
3. Rename scop->context to scop::param_context, and scop::ctx to
scop::isl_context

No functional changes intended. Passes regtest and bootstrap.
