ca05b607b7 Refer to -help instead of --help since this is what tools themselves say. 
Also, have tools output -help-hidden rather than refer to --help-hidden,
for consistency, and likewise adjust documentation.  This doesn't change
every mention of --help, only those which seemed clearly safe.

of AI3ldsbpo, AI3ldhpo, and AI3ldshpo in ARMInstrFormats.td in the process.

64b33dd9b7 Add a shared library for LLVM, named libLLVM2.7svn.(so|dylib), and add an 
--enable-shared configure flag to have the tools linked shared. (2.7svn is just
$(LLVMVersion) so it'll change to "2.7" in the release.)  Always link the
example programs shared to test that the shared library keeps working.

On my mac laptop, Debug libLLVM2.7svn.dylib is 39MB, and opt (for example) is
16M static vs 440K shared.

Two things are less than ideal here:
1) The library doesn't include any version information. Since we expect to break
the ABI with every release, this shouldn't be much of a problem. If we do
release a compatible 2.7.1, we may be able to hack its library to work with
binaries compiled against 2.7.0, or we can just ask them to recompile. I'm
hoping to get a real packaging expert to look at this for the 2.8 release.
2) llvm-config doesn't yet have an option to print link options for the shared
library. I'll add this as a subsequent patch.

9af06dfc83 Some dag combiner goodness: 
Transform br (xor (x, y)) -> br (x != y)
Transform br (xor (xor (x,y), 1)) -> br (x == y)
Also normalize (and (X, 1) == / != 1 -> (and (X, 1)) != / == 0 to match to "test on x86" and "tst on arm"

400e59ba21 Remove the NEON N2VSInt instruction class: it's only used in one place and 
since it has no pattern, there's not much point in distinguishing an "N2VS"
class for intrinsics anyway.

ea55421ec2 More cleanup for NEON: 
* Use "S" abbreviation for scalar single FP registers in class and pattern
names, instead of keeping the "D" (for "double") abbreviation and tacking on
an "s" elsewhere in the name.
* Move the scalar single FP register classes and patterns to be more
consistent with other definitions in the file.
* Rename "VNEGf32d" definition to "VNEGfd" for consistency.
* Deleted the N2VDIntsPat pattern; N2VSPat is good enough.
