    Change Struct_type::do_mangled_name to incorporate the field
    names even for hidden symbols. This is needed in cases where
    a package imports a type "S" that has an anonymous struct, e.g.
    
      // imported from some other package
      type S struct {
        X struct{ _ struct{} }
      }
    
    and then defines a local type that uses a structurally identical
    anonymous struct, e.g.
    
      // defined locally
      type T struct {
        U struct{ _ struct{} }
      }
    
    In the case above both types triggered the creation of hash/equal
    methods, but the method names were clashing (since both structs
    had the same mangled name).

When pushing a value into the literal pool the resulting decl might
get a higher alignment than the original expression depending on how a
target defines CONSTANT_ALIGNMENT.  Generating an RTX for the constant
pool access we currently use the alignment from the original
expression.  Changed with the attached patch.

This fixes a GCC 6 regression for S/390.  For arrays of string
constants as in the attached testcase encode_section_info is not able
to figure out that the constant pool slot is already properly aligned
since the mem_align field in the rtx is not set properly.

[PATCH, v2, rs6000] pr65479 Add -fasynchronous-unwind-tables when the -fsanitize=address option is seen.

All feedback from the earlier version has been taken into account now.

This patch adds the -fasynchronous-unwind-tables option to compilations when
the -fsanitize=address option is seen but not if any
-fasynchronous-unwind-tables options were already specified.
-fasynchronous-unwind-tables causes a full strack trace to be produced when
the sanitizer detects an error.  Without the full trace several of the asan
test cases fail on powerpc.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65479 for more information.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu,
powerpc64be-unknown-linux-gnu, and x86_64-pc-linux-gnu with no regressions.
Is this ok for trunk?
