Added support for the Builtin attribute.

The Builtin attribute is an attribute that can be placed on function call site that signal that even though a function is declared as being a builtin,

LoopVectorize: Don't store a reversed value in the vectorized value map

When we store values for reversed induction stores we must not store the
reversed value in the vectorized value map. Another instruction might use this
value.

This fixes 3 test cases of PR16455.

Add a convenience createUniqueDirectory function.

There are a few valid situation where we care about the structure inside a
directory, but not about the directory itself. A simple example is for unit
testing directory traversal.

PathV1 had a function like this, add one to V2 and port existing users of the
created temp file and delete it hack to using it.

Add CXXFLAGS back to the Link command.

This is essentially reverting one piece of 184793 to try to fix one of Apple's
buildbots.  I will check with Eric to see if this is OK or if we need to find
some other solution.

[SystemZ] Add conditional store patterns

Add pseudo conditional store instructions, so that we use:

    branch foo:
    store
foo:

instead of:

    load
    branch foo:
    move
foo:
    store

z196 has real 32-bit and 64-bit conditional stores, but we don't use
any z196 instructions yet.

R600: Remove alu-split.ll test

The purpose of this test was to check boundary conditions for the size
of an ALU clause.  This test is very sensitive to changes to the
optimizer or scheduler, because it requires an exact number of ALU
instructions in order to remain valid.  It's not good to have a test
this sensitive, because it is confusing to developers who implement
optimizations and then 'break' the test.

I'm not sure if there is a good way to test these limits using lit, but
if I can come up with replacement test that isn't as sensitive I'll add
it back to the tree.
