40d00c0979 Be more precise about which conversions of NaNs 
are Inexact.  (These are not Inexact as defined
by IEEE754, but that seems like a reasonable way
to abstract what happens:  information is lost.)

12cd5d041d Allow scalarrepl to treat an all-zero GEP just as bitcast. 
This includes not marking a GEP involving a vector as unsafe, but only when it
has all zero indices. This allows scalarrepl to work in a few more cases.

dcc1048912 Actually run Obj-C++ tests if llvm-gcc supports. 
Before there were two problems: (1) configure
turned "obj-c++" into "obj" in the langs line;
(2) the dejagnu library called it objc++ not
obj-c++.
Now the problem is that some of these tests don't
pass!

559ddbafc0 Clarify the relationship between byval and readonly/ 
readnone.  Make clearer that readnone functions do not
dereference pointer arguments.  Do not use the highly
ambiguous "side-effects" in the readonly description
(since such functions can have control flow side-effects,
such as throwing an exception, or looping for ever).

107e8f8b60 rewrite bswap matching to be more general, allowing arbitrary 
shifting and masking inside a bswap expr.  This allows it to handle
the cases from PR2842, which involve the intermediate 'or' 
expressions being shifted, not just the input value.

e22385630e Ignore loads from and stores to local memory (i.e. allocas)

Since the pass is currently run before SROA, this may be
quite helpful.  Requested by Chris on IRC.

638a8001c8 Fix a bug in the local allocator's liveness computation where it
