Summary:
With Visual Studio 2015 release, a part of runtime library was extracted
and now comes with Windows Kits. This patch enables clang to use
Universal CRT library if %INCLUDE or %LIB environment varaibles are not
specified.

The ACLE (ARM C Language Extensions) 2.0 allows the __fp16 type to be
used as a functon argument or return type (ACLE 1.1 did not).
The current public release of the AAPCS (2.09) states that __fp16 values
should be converted to single-precision before being passed or returned,
but AAPCS 2.10 (to be released shortly) changes this, so that they are
passed in the least-significant 16 bits of either a GPR (for base AAPCS)
or a single-precision register (for AAPCS-VFP). This does not change how
arguments are passed if they get passed on the stack.
This patch brings clang up to compliance with the latest versions of
both of these specs.
We can now set the __ARM_FP16_ARGS ACLE predefine, and we have always
been able to set the __ARM_FP16_FORMAT_IEEE predefine (we do not support
the alternative format).

to enable the use of external type references in the debug info

The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"

Error out if -mfloat-abi=hard or -mhard-float is specified on the command
line and the target ABI is APCS. Previously clang issued no warnings or
errors and just passed the option to the backend, which had no effect on
code generation for targets using APCS.
This commit corrects the patch commited in r245866, which didn't take into
account the fact that not all darwin targets use APCS.

For some reason, clang had been treating a command like:
clang -static -fPIC foo.c
as if it should be compiled without the PIC relocation model.
This was incorrect: -static should be affecting only the linking
model, and -fPIC only the compilation.
This new behavior also matches GCC.
This is a follow-up from a review comment on r245447.

doing assembly-only, and unify the Driver's PIC argument parsing.
On a few architectures, parsing of assembly files annoyingly depends
on whether PIC is enabled or not. This was handled for external 'as'
already (passing -KPIC), but was missed for calls to the standalone
internal assembler.
The integrated-as.s test needed to be modified to not expect
-fsanitize=address to be unused, as now fsanitize *IS* used for
assembly, since -fsanitize=memory can sometimes imply -fPIE, which the
assembler needs to know (gack!!).

-mkernel enables -fno-builtin and -fno-common by default, but allows -fbuiltin

same as "-fbuiltin" which is wrong, so fix that. Also fixes similar behaviour
when -fno-common is default.

This seems preferable to printing two warnings per unsupported option-
one warning about not supporting it, and one about not using it.
It also makes the '-Wno-' option do what you mean.

each other
It doesn't make any sense to enable -gmlt with -gsplit-dwarf, since
-gmlt is designed for on-line symbolication (and -gsplit-dwarf normally
emits all the -gmlt data into the .o anyway - so there's nothing to
split out except redundant/duplicate info).
With this change they override each other, -gmlt -gsplit-dwarf is the
same as -gsplit-dwarf and -gsplit-dwarf -gmlt is the same as -gmlt.

Copying the already existing code for x86 to ARM to set the correct CPU
features when using -mcpu=native. We can already detect the CPU name
but we were not setting the correct feature bits.
Moving fpu/hwdiv down to make sure they override whatever we set the
default to be.
No tests because this is native detection, and not all ARM-enabled builds
will hapen at a specific CPU, or even ARM. I have tested locally and it
works as expected.
Fixes PR12794.

The z13 vector facility has an associated language extension,
closely modeled on AltiVec/VSX. The main differences are:
- vector long, vector float and vector pixel are not supported
- vector long long and vector double are supported (like VSX)
- comparison operators return a vector rather than a scalar integer
- shift operators behave like the OpenCL shift operators
- vector bool is only supported as argument to certain operators;
some operators allow mixing a bool with a non-bool vector
This patch adds clang support for the extension. It is closely modelled
on the AltiVec support. Similarly to the -faltivec option, there's a
new -fzvector option to enable the extensions (as well as an -mzvector
alias for compatibility with GCC). There's also a separate LangOpt.
The extension as implemented here is intended to be compatible with
the -mzvector extension recently implemented by GCC.
Based on a patch by Richard Sandiford.

This patch allows Clang to pass on -Wa,-mfpu, -Wa,-mhwdiv and
-Wa,-mcpu to the integrated assembler (via target-features), but
-march is still not being passed, but validated.
In case the command line has both -mxxx and -Wa,-mxxx, we warn
that the naked one will not be used in assembler mode.
llvm-svn: 243353

To be able to handle -Wa, options in the assembler (ClangAs), we need to
make the handling of options based on the value of the options, not direct
Arguments from the list, since the list is immutable.
No functional change in this patch, but this allows validating of -Wa,-mfpu
and friends in the same way we validate -mfpu and friends, *just* for the
assembler.

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.
