I don't like to reconfigure and rebuild most of LLVM to repro these issues.
Is it possible to pass this to llvm-lit.py somehow to get %clang_cc1 to
expand to clang -cc1 -triple $mytriple?

I can reproduce with LIT_USE_INTERNAL_SHELL=0. The problem is that this
test relies on -Wpadded, which is only implemented in the Itanium record
layout code. I think we can safely give headersearch.cpp a triple and
reland.
