Subject: [PATCH] Enable SSP and PIE by default

This is a minimal set of changes needed to make clang use SSP and PIE by
default on Arch Linux. Tests that were easy to adjust have been changed
accordingly; only test/Driver/linux-ld.c has been marked as "expected
failure" due to the number of changes it would require (mostly replacing
crtbegin.o with crtbeginS.o).

Doing so is needed in order to align clang with the new default GCC
behavior in Arch which generates PIE executables by default and also
defaults to -fstack-protector-strong. It is not meant to be a long term
solution, but a simple temporary fix.

Hopefully these changes will be obsoleted by the introduction upstream
of a compile-time option (https://bugs.llvm.org/show_bug.cgi?id=13410)
