[Bug tree-optimization/32901] New: [4.1 regression] bitfield constants with multiple bitfields take up space in .data

["j at uriah dot heep dot sax dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When defining a bitfield constant where multiple bitfields have initializing
values, this constant is moved into .data in GCC 4.1.  GCC 3.x could realize
it can be written and assigned as a single integer number.  GCC 4.x only
realizes this situation as long as a single bitfield is initialized.

Verified on i386 and avr targets, so this is apparently completely independent
of the target CPU.
