[PATCH] Mangling of member-expressions involving anonymous unions.

[Tomasz Miąsko]

Hi rsmith,

When mangling member-expressions, mangle only access to first named member,
ignoring unnamed ones in anonymous unions. This fixes crash reported in bug
report 15542, and results in behaviour consistent with GCC.
