Mark all x86 Int_ and _Int patterns as isCodeGenOnly so the disassembler table builder doesn't need to string match them to exclude them.

The separate Xcode project generated for Clang is putting the clang
executables into the same location where the LLVM executables are
going. This is wrong, and breaks the Clang build because we try to
create clang++ and clang-cl symlinks in the wrong place and to the
wrong place.

As a stop-gap to get these builds working again, teach the symlink
generation to point into the LLVM executable directory instead.

When building Clang separately from LLVM with CMake, one should set
the path of llvm-config via the cache variable LLVM_CONFIG.

The backend string is only verified when available as it's possible to run
clang IRGen for targets that haven't been built or don't exist in LLVM.

This patch makes it possible to select the ABI with -mattr. It will be used to
forward clang's -target-abi option to llvm's CodeGen.

When there are cycles in the value graph we have to be careful interpreting
"Value*" identity as "value" equivalence. We interpret the value of a phi node
as the value of its operands.
When we check for value equivalence now we make sure that the "Value*" dominates
all cycles (phis).

%0 = phi [%noaliasval, %addr2]
%l = load %ptr
%addr1 = gep @a, 0, %l
%addr2 = gep @a, 0, (%l + 1)
store %ptr ...

Before this patch we would return NoAlias for (%0, %addr1) which is wrong
because the value of the load is from different iterations of the loop.

Tested on x86_64 -mavx at O3 and O3 -flto with no performance or compile time
regressions.

During the years there have been some attempts at figuring out how to
align byval arguments. A look at the commit log suggests that they
were

* Use the ABI alignment.
* When that was not sufficient for x86-64, I added the 's' specification to
  DataLayout.
* When that was not sufficient Evan added the virtual getByValTypeAlignment.
* When even that was not sufficient, we just got the FE to add the alignment
  to the byval.

This patch is just a simple cleanup that removes my first attempt at fixing the
problem. I also added an AArch64 implementation of getByValTypeAlignment to
make sure this patch is a nop. I also left the 's' parsing for backward
compatibility.

I will send a short email to llvmdev about the change for anyone maintaining
an out of tree target.

Remove UnaryTypeTraitExpr and switch all remaining type trait related handling
over to TypeTraitExpr.

The UTT/BTT/TT enum prefix and evaluation code is retained pending further

This is part of the ongoing work to unify type traits following the removal of
BinaryTypeTraitExpr in r197273.

 1) Teach ExpectAndConsume() to emit expected and expected-after diagnostics
    using the generic diagnostic descriptions added in r197972, eliminating another
    set of trivial err_expected_* variations while maintaining existing behaviour.

 2) Lift SkipUntil() recovery out of ExpectAndConsume(). The Expect/Consume
    family of functions are primitive parser operations that now have the
    well-defined property of operating on single tokens. Factoring out recovery
    exposes opportunities for more consistent and tailored error recover at the
    call sites instead of just relying on a bottled SkipUntil formula.
