Need -O1 or better to have these builtins lowered to

Because we promote SSE logical ops and loads to v2i64, we often end up generate
code that cross integer / floating point domains (e.g. generate pxor / pand for
logical ops on floating point value, movdqa to load / store floating point SSE
values). Given that, it's better to use movaps instead of movdqa and movups
instead of movdqu. They have the same latency but the "aps" variants are one
byte shorter.
If the domain crossing problem is a real performance issue, then we will have to
fix it with dynamic programming based isel.

For PR1553:
Change the keywords for the zext and sext parameter attributes to be
zeroext and signext so they don't conflict with the keywords for the
instructions of the same name. This gets around the ambiguity.

Don't use * in XFAIL line unless you want it to XFAIL on everything. I don't believe you can use true regular expressions here. It will just look for those keywords. Please test this on sparc and see if they still are xfailed.

Missed the case where alloca is used but the stack size (not including callee-saved portion) is zero. Thanks Dan.

For PR1558:
Move tests that have C/C++ sources into the appropriate directory. This
allows them to be selected for testing based on whether llvm-gcc is
present or not.

Unbreak the build by putting calls to free into the implementation file and

Take advantage of undefined behavior if the source program tries to GEP
beyond the end of an alloca to make FastDSE faster and more aggressive.

Normally, we don't want to install and we only need to build tools.

No, we're not looking for a directory named /config.status.
Sigh .. fix copy & paste error.

In ModuleInfo.txt, make sure that the script being executed can be
found by prepending a .
In build-for-llvm-top.sh, dereference variables for exansion.

Prepare for the future when llvm doesn't depend on llvm-gcc-4-0.
This also avoids a fork bomb from the llvm-top/build script which
doesn't know how to handle cycles in the dependence graph.
