This still breaks this m68k test case:
http://gcc.gnu.org/ml/gcc/2007-04/msg00830.html

BTW the previous patch broke the m68k bootstrap and this doesn't make me 
very confident this one will do better.

A specific comment about the patch, it might be better to keep combining 
multiple fields, if they don't match the alignment exactly (e.g. as in the 
above test case).
Even better would be if the per field copy of the sra pass would be 
completely suppressed if the structure is already likely to be in a 
register anyway.

bye, Roman
