When compiler-rt is selected as the runtime library for Linux targets
use its crtbegin.o/crtend.o implemenetation rather than platform one
if available.

In r339807, I broke linking the builtins libraries for simulator targets, which itself was bad, but turns out it was all completely untested and marked with FIXME in the test suite.
This fixes all the test cases so they actually work, and fixes the bug I introduced in r339807.

This change causes issues with distributed build systems, which may only
have compiler binaries without any runtime libraries. See discussion
about this on https://reviews.llvm.org/D15225.

The runtime libraries of sanitizers are built in compiler-rt, and Clang
can be built without compiler-rt, or compiler-rt can be configured to
only build certain sanitizers. The driver should provide reasonable
diagnostics and not a link-time error when a runtime library is missing.
This patch changes the driver for OS X to only support sanitizers of
which we can find the runtime libraries. The discussion for this patch
explains the rationale

This patch introduces the -fwhole-program-vtables flag, which enables the
whole-program vtable optimization feature (D16795) in Clang.

Summary:
Do not include default sanitizer blacklists into -M/-MM/-MD/-MMD output.
Introduce a frontend option -fdepfile-entry, and only insert them
for the user-defined sanitizer blacklists. In frontend, grab ExtraDeps
from -fdepfile-entry, instead of -fsanitize-blacklist.

For now tsan_cxx and msan_cxx contain only operator new/delete
replacements. In the future, when we add support for running UBSan+TSan
and UBSan+MSan, they will also contain bits ubsan_cxx runtime.

This refactors some of the Darwin toolchain classification to give a more solid
distinction between the three primary Darwin platforms (OS X, IOS and IOS
simulator) so that a 4th choice can be added temporarily: embedded MachO
targets.
Longer term, this support will be factored out into a separate class and no
longer classified as "darwin-eabi", but the refactoring should still be useful.

linker via --dynamic-list instead of using --export-dynamic. This reduces the
size of the dynamic symbol table, and thus of the binary (in some cases by up
to ~30%).
