getelementptr. Despite only doing so in the case where x is a known
array object and c can be converted to an index within range, this
could still be invalid if c is actually the address of an object
allocated outside of LLVM. Also, SCEVExpander, the original motivation
for this code, has since been improved to avoid inttoptr+ptroint in
more cases.

x86 and x86_64 on UNIX systems. Only OS X 10.6.2 (x86_64) and 32bit CentOS 5.2
with gcc 4.1.2 were tested. ARM UNIX build triggered failure motivating this
modification, as it seems that the ARM ABI does not support _Unwind_GetIP(...),
_Unwind_SetGR(...), and _Unwind_SetIP(...). From doing a quick browse of:
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0038a/IHI0038A_ehabi.pdf,
it seems as if all other exception related apis are supported. Looks like
the port can be done to ARM. Thanks to Xerxes Rånby <xerxes@zafena.se> for
pointing out this error.

capable compilers (which could be llvm-gcc or clang).

Comes in two parts:
 1. Use --with-clang=path/to/clang/compiler to select an installed clang, or
    --with-built-clang to have the makefiles use the clang which will be built
    as the LLVM capable compiler. If neither is given, --with-built-clang will
    be used if the Clang sources are checked out into the standard location
    (tools/clang).

 2. Use --with-llvmcc={llvm-gcc,clang,none} to specify which LLVM capable
    compiler to use. If not given, then llvm-gcc will be used if available,
    otherwise Clang.

Makefile support still to come.

Eric, Doug, Chris, seem reasonable?

Needed to correctly handle things like 'llvmc -framework Foo foo.o -framework
Bar bar.o' - before this commit all '-framework' options would've been grouped
together in the beginning.

Due to our dependence on CommandLine this turned out to be a giant hack; we will
migrate away from CommandLine eventually.
