Sometimes compile_commands.json databases are created without an
absolute path for the driver in the command field. By default the driver
name is appended to the current directory, however if no driver is found
in that location assume it was in the default PATH and try finding it
there

In some cases system includes extractions is not enough, we also need target specific defines.
The problems appears when clang default target is not the same as toolchain's one (GCC cross-compiler, MinGW on Windows).
After this patch `query-driver` also extracts target and adds `--target=<extracted target>` compile option.

The escaped parens seem to confuse the combination of lit, cygwin
quoting, and cygwin's sed. unxutils sed in cmd.exe is fine with both
forms, so use the extended regex form that doesn't need an escaped
paren.

Summary:
gcc invokes cc1 through a path deduced from argv[0] therefore it must
be correctly set.
Also it prints the search path to stderr not stdout, this also applies to clang.

Summary:
Some custom toolchains come with their own header files and compiler
drivers. Those compiler drivers implicitly know about include search path for
those headers. This patch aims to extract that information from drivers and add
it to the command line when invoking clang frontend.
