f85e74cc87 Fix configure issue where configure 
turned "obj-c++" into "obj" in the langs line.
Update configure script.

8c3f8b6dea Add MBB successors and physreg Uses in the same order that 
SDISel typically adds them in. This makes it a little easier
to compare FastISel output with SDISel output.

1e9e8c3bd5 Avoid emitting redundant materializations of integer constants 
for things like null pointers, which at this level aren't
different from regular integer constants.

145b828014 Instead of emitting an implicit use for the super-register of 
X86::CL that was used, emit an EXTRACT_SUBREG from the CL
super-register to CL. This more precisely describes how the
CL register is being used.

2bdc07b398 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

e4a4245906 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.

2df5eec2ff 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.)

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.

96f945267c 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!

edb05dfe48 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).
