ae1c6198f9 S/390: Replace LDER with LDR. 
For performance reasons it is important to write the full 64 bits of
an FPR target reg even when dealing with 32 bit values.  So we chose
lder over ler for 32 bit float register moves.  lder zero-extends the
32 bit value from the source reg to 64 bit in the target.  However,
since it actually doesn't matter whether we write the upper 32 bits
with zeros or with any other garbage we can also use ldr instead.  It
is bit shorter and therefore will do good for I-Cache usage.

3e4be43f69 S/390: Memory constraint cleanup 
This fixes an issue with the long displacement memory address
constraints S and T.  These were defined to only accept long
displacement addresses.  This is wrong since a memory constraint must
not reject an address with a 0 displacement.  Reload relies on being
able to turn an invalid memory address into a valid one by reloading
the address into a base register.  The S and T constraints would
reject such an address.

This isn't really a problem for the backend since we used the
constraints with that knowledge there but it is a problem for people
writing inline assemblies.

dc236a9d78 sbitmap: Remove popcount 
In r193072 sbitmap_popcount was removed, so we cannot ask for the popcount
of an sbitmap anymore.  Nothing calls sbitmap_alloc_with_popcount either.
This patch removes everything else popcount-related from sbitmap.
