3d73bce2d0 don't hoist FP additions into unconditional adds + selects. This 
could theoretically introduce a trap, but is also a performance issue.
This speeds up ptrdist/ks by 8%.

dc024674ff Fix PR1146: parameter attributes are longer part of 
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

eacb7020ec For PR950: 
Update the test suite to accommodate the change from signed integer types
to signless integer types. The changes were of only a few kinds:

1. Make sure llvm-upgrade is run on the source which does the bulk of the
   changes automatically.

2. Change things like "grep 'int'" to "grep 'i32'"

3. In several tests bitcasting caused the same name to be reused in the
   same type plane. These had to be manually fixed. The fix was (generally)
   to leave the bitcast and provide the instruction with a new name. This
   should not affect the semantics of the test. In a few cases, the
   bitcasts were known to be superfluous and irrelevant to the test case
   so they were removed.

4. One test case uses a bytecode file which needed to be updated to the
   latest bytecode format.
