Nuno Lopes 9a04782fda add support for running the test suite with valgrind. to run it just type 'make VG=1', as in clang 
beware of the 42000 leaks reported by valgrind in the Constant.cpp + Type.cpp files. it needs fixing IMHO

Dale Johannesen 7221af384d Mark negative-zero-to-int conversion as Inexact, 
since -0.0 can't be represented as an int.
This prevents llvm from reducing -0.0 to a
load-and-convert of int 0.  Fixes
ieee.exp/mzero[2356].c in gcc testsuite.

Dale Johannesen 6c6729f3a8 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.)

Matthijs Kooijman cbe5e16eb5 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.

Duncan Sands bae7a517cc 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!

Duncan Sands 2a1d8bace1 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).

Chris Lattner 917a6c1343 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.
