Make tree_expr_nonnegative_warnv_p recurse into SSA names

The upcoming patch to move sqrt and cbrt simplifications to match.pd
caused a regression because the (abs @0)->@0 simplification didn't
trigger for:

        (abs (convert (abs X)))

The simplification is based on tree_expr_nonnegative_p, which at
the moment just gives up if it sees an SSA_NAME.

This patch makes tree_expr_nonnegative_p recurse into SSA name
definitions, but limits the depth of recursion to a small number
for the reason mentioned in the comment (adapted from an existing
comment in gimple_val_nonnegative_real_p).  The patch reuses code
in tree-vrp.c, moving it to gimple-fold.c.  It also replaces calls
to gimple_val_nonnegative_real_p with calls to tree_expr_nonnegative_p.

A knock-on effect is that we can now prove _i_589 < 0 is false in
sequences like:

      i_1917 = ASSERT_EXPR <i_1075, i_1075 == 0>;
      _i_589 = (const int) i_1917;
      _i_1507 = ASSERT_EXPR <_i_589, _i_589 < 0>;

This defeats an assert in tree-vrp.c that ASSERT_EXPR conditions
are never known to be false.  Previously the assert only ever used
local knowledge and so would be limited to cases like x != x for
integer x.  Now that we use global knowledge it's possible to prove
the assertion condition is false in blocks that are in practice
unreachable.  The patch therefore removes the assert.

Bootstrapped & regression-tested on x86_64-linux-gnu.  I didn't write
a specific test because this is already covered by the testsuite if
the follow-on patch is also applied.

compiler: Record each import as a distinct alias.

    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.
