to operate "as if" in a certain working directory.
- For now, we just implement this by changing the actual working directory, but
eventually we would want to handle this transparently. This is useful to
avoid an extra exec() pair in some situations, and will be something we would
want to support for more flexibility in using the Clang libraries.

as well as the search path printed by -print-search-dirs.
The main purpose of this change is to cause -print-file-name=include
to print the path to the include directory under Clang's resource
directory, instead of the system compiler's include directory, whose
header files Clang may not be able to parse. Some build scripts will
do something like:
$(CC) -nostdinc -I`$(CC) -print-file-name=include`
to exclude all header paths except the compiler's.

cases we want the prefix to be the original file name less the suffix. For an
input such as test.c to named temporary would be something like test-3O4Clq.o

As a note this will need a little bit of refactoring in the class
hierarchy to separate it out for different verifiers based on input type.

use in KEXTs. However, users/Xcode still need to tweak the linker flags to do
the right thing, and end up using -Xlinker, for example. Instead, have the
driver "do the right thing" when linking when -fapple-kext is present on the
command line, and we should have Xcode use -fapple-kext instead of setting other
flags like -Xlinker -kext or -nodefaultlibs.

Patch by Matthieu Monrocq with tweaks by me to avoid StringRefs in the static
diagnostic data structures, which resulted in a huge global-var-init function.
Depends on llvm commit r132046.

Put the logic for deciding the default name for gcc/g++
in the only place that actually cares about it.
This also pushes an ifdef out of the generic driver code
to a little further down, when the target is actually known.
Hopefully it can be changed into just a runtime check
in the future.

Pass down the correct C->getArgs, but keep it with the original
DerivedArgList type. Slightly adjust the MakeIndex call for the
different base type. This unbreaks the handling of --no-mangle on Darwin.

provide necessary default based on e.g. environment value (e.g. for
"arm-eabi" triple, etc.)
