regardless of the architecture).
- This is a good default for development & testing; for example without this
any tests using 'clang' in the test suite will fail on PowerPC, since the
driver will avoid using clang.
- We don't want to actually ship something built this way, but that should be
handled via some sort of configuration file.

using -traditional and -traditional-cpp with clang an error because
it's unsupported in clang and causes a significant change in the
semantics of the language.

with a particular system root directory and can be used with a different
system root directory when the headers it depends on have been installed.
Relocatable precompiled headers rewrite the file names of the headers used
when generating the PCH file into the corresponding file names of the
headers available when using the PCH file.

- Not all tools give good error messages, and sometimes the tool can fail w/o
any error (for example, when signalled).
- We suppress this message when the failing command is the compiler and it
failed normally (exit code == 1), under the assumption that it gave a good
diagnostic.
For example, for a linker failure we now get:
--
ddunbar@lordcrumb:tmp$ clang a.c b.c
ld: duplicate symbol _x in /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-bXYITq.o and /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-6uK4jD.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
--
For a compiler crash we get:
--
ddunbar@lordcrumb:tmp$ clang t.i
Assertion failed: (CGT.getTargetData().getTypeAllocSizeInBits(STy) == RL.getSize()), function layoutStructFields, file CodeGenTypes.cpp, line 573.

... stack trace and virtual stack trace follow ...
clang: error: compiler command failed due to signal 6 (use -v to see invocation)
--
But for a regular compilation failure we get the usual:
--
ddunbar@lordcrumb:tmp$ clang c.c
c.c:1:6: error: invalid token after top level declarator

1 diagnostic generated.

- We could just warn about -fno-unit-at-a-time, but in practice people using it
probably aren't going to get what they want out of clang.
Also, use "clang" specified error for unsupported things instead of driver
unsupported error.

- This commit has some messy stuff in it to extend string lifetimes, but that
will go away once we switch to using the enum'd Triple interfaces.
