[Bug target/39179] Wrong code in c++ for const members initialized in external file

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The problem is that targetm.binds_local_p returns true for

 <var_decl 0xb7866000 k
    type <integer_type 0xb785edd0 unsigned int readonly unsigned SI
        size <integer_cst 0xb778b4a4 constant 32>
        unit size <integer_cst 0xb778b1f8 constant 4>
        align 32 symtab 0 alias set -1 canonical type 0xb785edd0 precision 32
min <integer_cst 0xb778b4c8 0> max <integer_cst 0xb778b480 4294967295>>
    readonly used public static unsigned external nonlocal decl_3 decl_5 decl_6
SI file t.ii line 2 col 27 size <integer_cst 0xb778b4a4 32> unit size
<integer_cst 0xb778b1f8 4>
    align 32 context <record_type 0xb785ec30 K>
    chain <type_decl 0xb785ed00 K>>

though probably nobody thought of handling TREE_STATIC && DECL_EXTERNAL being
true at the same time.  Thus, this looks like a possible C++ FE problem to me?

A simple fix would be for i386_pe_binds_local_p to return false if
DECL_EXTERNAL is set, as this is what default_binds_local_p_1 does.
Or better, it should dispatch to default_binds_local_p_1 and only
adjust the shlib flag according to DECL_DLLIMPORT_P.
