Tim Northover 6f3ff22e73 Support watchOS and tvOS driver options
This patch should add support for almost all command-line options and
driver tinkering necessary to produce a correct "clang -cc1"
invocation for watchOS and tvOS.

Bruno Cardoso Lopes 57737529fe [DarwinDriver] Use -lto_library to specify the path for libLTO.dylib
Usually, when using LTO with a clang installation newer than the
system's one, there's a libLTO.dylib version mismatch and LTO fails. One
solution to this is to make ld point to the right libLTO.dylib by
changing DYLD_LIBRARY_PATH.

However, ld64 supports specifying the complete path to the desired
libLTO.dylib through the -lto_library option. This commit adds support
for the clang driver to use this option whenever it's capable of finding
a libLTO.dylib in clang's installed library directory. This way, we
don't need to rely on DYLD_LIBRARY_PATH nor get caught by version
mismatches.

Bob Wilson 771b7cd812 Remove a FIXME: use the ios_simulator_version_min linker option consistently.
This was previously only used when explicitly requested with a command line
option because it had to work with some old versions of the linker when it
was first introduced. That is ancient history now, and it should be safe to
use the correct option even when using the IPHONEOS_DEPLOYMENT_TARGET
environment variable to specify that the target is the iOS simulator.
Besides updating the test for this, I also added a few more tests for the
iOS linker options.

Tim Northover a2ee433c8d ARM64: initial clang support commit.
This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.

As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

Bob Wilson 5cfc55e49f Fix an assertion failure when building for the iOS simulator. rdar://15959009
When building for i386 or x86_64 with IPHONEOS_DEPLOYMENT_TARGET set in the
environment, the toolchain correctly recognizes that the target platform is
the iOS simulator. The code in Darwin::addMinVersionArgs was not updated for
svn 197148, where isTargetIPhoneOS() was widely replaced by isTargetIOSBased().
This is kind of a strange case, though, because we probably ought to be
passing -ios_simulator_version_min to the linker, but according to the FIXME
in the code, we intentionally avoid that unless the -mios-simulator-version-min
option was used. I don't know whether it is safe to change that yet, so
for now, I am just fixing the assertion failure.

Bob Wilson 74b6cd15ed Stop linking with crt1.o etc. for the iOS simulator. <rdar://problem/11800973>
Recent versions of the iOS simulator no longer require linking with the
crt1.o, dylib1.o, or bundle1.o files. The relevant code is now included in
libSystem for the simulator.

Bob Wilson 9914a02114 Propagate "-arch x86_64h" setting to the linker. <rdar://problem/15711488>
This is a follow-up to r194907, which added a new -arch setting to make it
easier to specify AVX2 targets. The "-arch x86_64h" option needs to be passed
on to the linker, but it was getting canonicalized to x86_64 by the code
in getArchTypeForDarwinArchName.

Bob Wilson 1e148fe064 When using -pg targeting OS X 10.8, pass -no_new_main to the linker.
By default on OS X 10.8, we don't link with a crt1.o file and the linker
knows to use _main as the entry point.  But, when compiling with -pg, we
need to link with the gcrt1.o file, and the linker needs to be told to use
the "start" symbol as the entry point.  The -no_new_main linker option does
that last part.  <rdar://problem/11491405>

Ted Kremenek e65b086e07 Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,
NSNumber, and boolean literals.  This includes both Sema and Codegen support.
Included is also support for new Objective-C container subscripting.

My apologies for the large patch.  It was very difficult to break apart.
The patch introduces changes to the driver as well to cause clang to link
in additional runtime support when needed to support the new language features.

Docs are forthcoming to document the implementation and behavior of these features.

Bob Wilson 9d3f7af8c3 Fix more fallout from the introduction of "macosx" and "ios" triples.
The Darwin toolchain constructor was assuming that all Darwin triples would
have an OS string starting with "darwin".  Triples starting with "macosx"
would misinterpret the version number, and "ios" triples would completely
miss the version number (or worse) because the OS name is not 6 characters
long.  We lose some sanity checking of triple strings here, since the
Triple.getOSVersion function doesn't do all the checking that the previous
code did, but this still seems like a step in the right direction.

Daniel Dunbar ef889c7c9b Driver/Darwin: When invoking the linker, automatically pass -object_path_lto so
