Remove the llvm.nacl.thread.stack.padding intrinsic

Remove the llvm.nacl.thread.stack.padding intrinsic

This intrinsic is no longer used by untrusted code's libpthread.
Instead the system (the IRT and/or TCB) is responsible for aligning
the stack in new threads.

This is my first PNaCl-LLVM change.  Are there trybots I can run this through?

Unfortunately there aren't yet; (currently you can still only try changes in the
nacl repo). now that we've switched to git i will hopefully soon make a script
like the gnu toolchain's toolchain-git-try.sh.

lgtm

I've added you to nacl-pnacl-committers in gerrit, so git-cl should just be able
to push this change in its usual way.

thanks for taking care of this btw.
