Richard Smith cff3cde28b Split ubsan runtime into three pieces (clang part):
* libclang_rt-san-* is sanitizer_common, and is linked in only if no other
   sanitizer runtime is present.
 * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on
   a C++ ABI library, and is always linked in.
 * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a
   C++ ABI library, and is only linked in when linking a C++ binary.

This change also switches us to using -whole-archive for the ubsan runtime
(which is made possible by the above split), and switches us to only linking
the sanitizer runtime into the main binary and not into DSOs (which is made
possible by using -whole-archive).

The motivation for this is to only link a single copy of sanitizer_common
into any binary. This is becoming important now because we want to share
more state between multiple sanitizers in the same process (for instance,
we want a single shared output mutex).

The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't
need this complexity.

Hans Wennborg c5f4c36029 Fix redundant comparison in gcc::Common::ConstructJob.
We were checking "Arch == llvm::Triple::x86_64 || Arch
== llvm::Triple::x86_64", but the rhs should actually check for
powerpc64.

Found while experimenting with a potential new Clang warning.

Jim Grosbach 061dabf7df Driver: -ccc-install-dir should affect cc1 -resource-dir
-ccc-install-dir is supposed to cause the compiler to behave as-if it
were installed in the indicated location. It almost does, but misses
anything that's relying on the resource directory (libc++ header search,
in particular). The resource dir is resolved too early, before command
line args are handled.

The fix is simply to move handling of the resource dir until after we
know if a -ccc-install-dir is present.

Ted Kremenek 4b3ecba537 Disallow using -fmodules with -no-integrated-as.
Modules enables features such as auto-linking, and we simply do not want to
support a matrix of subtly enabled/disabled features depending on whether or
not a user is using the integrated assembler.

It isn't clear if this is the best place to do this check.  For one thing,
these kind of errors are not caught by the serialized diagnostics.

Chandler Carruth 58d6eb6d03 Check for warnings in a bunch of the linker invocations, and add one
with both -static-libgcc and -static on the commandline.

Fix a warning in the latter case due to a backwards short circuiting ||
operator in the driver. No real functionality changed here, just allows
the driver to properly consume -static-libgcc when -static is also
specified.

Bob Wilson 2616e2ec85 Use -mno-implicit-float by default for kernel/kext code. <rdar://13177960>
Apple's kernel engineers have been expecting this behavior even though
we've never implemented it before, as far as I can tell. In recent months,
clang has gotten better at using vector instructions to optimize memcpy-like
operations, and that has exposed problems when vector/floating-point
instructions are used in kexts that don't support that. This behavior also
matches what Apple's GCC did for PowerPC targets.

Bob Wilson 2cc9690f5e Recognize -mno-implicit-float option for x86 as well as ARM. <rdar://13180731>
For x86 targets, we've been using the -msoft-float option to control passing
the no-implicit-float option to cc1. Since the -mno-implicit-float option is
now accepted by the driver, this just makes it work for x86 the same as it
does for ARM targets.
