This is recommit of r302775, reverted in r302777 due to a fail in
clang-tidy. Original mesage is below.
Now if clang driver is given wrong arguments, in some cases it
continues execution and returns zero code. This change fixes this
behavior.
The fix revealed some errors in clang test set.
File test/Driver/gfortran.f90 added in r118203 checks forwarding
gfortran flags to GCC. Now driver reports error on this file, because
the option -working-directory implemented in clang differs from the
option with the same name implemented in gfortran, in clang the option
requires argument, in gfortran does not.
In the file test/Driver/arm-darwin-builtin.c clang is called with
options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed
in r191435 and now clang reports error on this test.
File arm-default-build-attributes.s uses option -verify, which is not
supported by driver, it is cc1 option.
Similarly, the file split-debug.h uses options -fmodules-embed-all-files
and -fmodule-format=obj, which are not supported by driver.
Other revealed errors are mainly mistypes.

This matches the cl.exe behavior (tested with 18.00.31101). In order to
specify an output file for /P, use the /Fi option instead.

When it's used without an argument, the default file name is
used. The same goes for /Fe.
Also, allow using /Fo, /Fa and /Fe with multiple inputs if they
don't have an argument.
llvm-svn: 222164
Summary:
cl.exe recognizes /o as a deprecated and undocumented option similar to
/Fe. This patch adds support for this option to clang-cl for /Fe, /Fo
and /Fi. It also ensures that the last option among /o and /F* wins,
if both specified.
This is required at least for building autoconf based software, since
autoconf uses -o to specify the executable output.
This fixes http://llvm.org/PR20894.
Test Plan: The patch includes automated tests.

This adds support for outputing the assembly to a file during compilation.
It does this by changing the compilation pipeling to not use the integrated
assembler, and keep the intermediate assembler file.

I put in the warnings because MSVC has them, but I don't think they're very
useful.
Clang does not warn about overriding flags in general, e.g. it's perfectly
fine to have -fomit-frame-pointer followed by -fno-omit-frame-pointer.
We should focus on warning where things get confusing, such as with the
/TP and /TC options. In "clang-cl /TC a.c /TP b.cc", the user might not
realize that the /TP flag will apply to both files, and we warn about that.

This adds driver support for building DLLs (the /LD and /LDd flags).
It basically does two things: runtime selection and passing -dll and
-implib to the linker.

We already use .obj as extension when the user provides a stem file
name (via /Fo), but were failing in the most basic case when the file
name is based on the input file.
