Currently trigger to select hard-float linker is only based of -gnueabihf

We had multiple bugs here:
- We didn't support multiple optimization options in one argument.
e.g. -O2y-
- We didn't correctly expand -O[12dx] to their respective options.
- We treated -O1 as clang -O1 instead of clang -Os.
- We treated -Ox as clang -O3 instead of clang -O2. In fact, cl's -Ox
option is *less* powerful than cl's -O2 option despite -Ox described
as "Full Optimization".
This fixes PR24003.

Currently, for --rtlib=compiler-rt on GNU systems, we're assuming
that one has libgcc_s and libgcc_eh as low-level libraries, which
when used in conjunction with -lunwind or -lc++abi, breaks that
assumption.
My original fix was wrong, and this patch reverts it to prepare for
a new flag to choose the unwinder/C++ libraries. For the time being,
people can use "-lgcc_s -lgcc_eh" or "-lunwind -lc++abi" or any
combination they need explicitly.

Now clang should be able to use compiler-rt and libc++ on mingw.

Currently, -save-temp will cause ObjCARC optimization to be dropped,
sanitizer pass to run early in the pipeline, and profiling
instrumentation to run twice.
Fix the issue by properly disable all passes in the optimization
pipeline when generating bitcode output and parse some of the Language
Options even when the input is bitcode so the passes can be setup
correctly.

clang-cl, users can use the '-Xclang -fexceptions -Xclang

We don't need any more bug reports from users telling us that MSVC-style

All of the ABIs we support are altivec style anyhow and so the option

The function is massively large and GCC is emitting stack overflow
errors when building it (stack, as counted by the compiler, grows to
more than 16Kb).
The new flag processing logic added in r241825 took it over the limit.
llvm-svn: 241918
This patch adds support for specifying where the profile is emitted in a
way similar to GCC. These flags are used to specify directories instead
of filenames. When -fprofile-generate=DIR is used, the compiler will
generate code to write to <DIR>/default.profraw.
The patch also adds a couple of extensions: LLVM_PROFILE_FILE can still be
used to override the directory and file name to use and -fprofile-use
accepts both directories and filenames.
To simplify the set of flags used in the backend, all the flags get
canonicalized to -fprofile-instr-{generate,use} when passed to the
backend. The decision to use a default name for the profile is done
in the driver.

--Original Commit Message--
Pass down the -flto option to the -cc1 job, and from there into the
CodeGenOptions and onto the PassManagerBuilder. This enables gating
the new EliminateAvailableExternally module pass on whether we are
preparing for LTO.
If we are preparing for LTO (e.g. a -flto -c compile), the new pass is not
included as we want to preserve available externally functions for possible
link time inlining.

On Windows the user may invoke the linker directly, so we might not have an
opportunity to add runtime library flags to the linker command line. Instead,
instruct the code generator to embed linker directive in the object file
that cause the required runtime libraries to be linked.
We might also want to do something similar for ASan, but it seems to have
its own special complexities which may make this infeasible.

Classes in Tools.h inherit ultimately from Tool, which is a noun,
but subclasses of Tool were named for their operation, such as "Compile",
wherein the constructor call "Compile(args...)" could be misconstrued
as actually causing a compile to happen.
Likewise various other methods were not harmonious with their effect,
in that "BuildLinker()" returned a "new namespace::Link(...)"
instead of a "new namespace::Linker(...)" which it now does.
Exceptions: Clang and ClangAs are un-renamed. Those are their rightful names.
And there is no particulary great way to name the "Lipo-er" and a few others.

Summary:
This is unfortunate, but would let us land http://reviews.llvm.org/D10467,
that makes ToolChains responsible for computing the set of sanitizers
they support.
Unfortunately, Darwin ToolChains doesn't know about actual OS they
target until ToolChain::TranslateArgs() is called. In particular, it
means we won't be able to construct SanitizerArgs for these ToolChains
before that.
This change removes SanitizerArgs::needsLTO() method, so that now
ToolChain::IsUsingLTO(), which is called very early, doesn't need
SanitizerArgs to implement this method.
Docs and test cases are updated accordingly. See
https://llvm.org/bugs/show_bug.cgi?id=23539, which describes why we
start all these.

This change passes through C and assembler jobs to Movidius tools by
constructing commands which are the same as ones produces by the examples
in the SDK. But rather than reference MV_TOOLS_DIR to find tools,
we will assume that binaries are installed wherever the Driver would
find its native tools. Similarly, this change assumes that -I options
will "just work" based on where SDK headers get installed, rather than
baking into the Driver some magic paths.
