add support for the OpenCL __private, __local, __constant and
__global address spaces, as well as the __read_only, _read_write and
__write_only image access specifiers.  Patch originally by ARM;
language-specific address space support by myself.

Remove '-Xclang' and '-mllvm' entries from Clang man page.  The later is only available in debug builds and the former is not supposed to be used by end-users.

The llvm.dbg.value intrinsic refers to SSA values, not virtual registers, so we
should be able to extend the range of a value by tracking that value through
register copies. This greatly improves the debug value tracking for function
arguments that for some reason are copied to a second virtual register at the
end of the entry block.

We only extend the debug value range where its register is killed. All original
llvm.dbg.value locations are still respected.

Copies from physical registers are ignored. That should not be a problem since
the entry block already adds DBG_VALUE instructions for the virtual registers
holding the function arguments.

 - We don't really support the majority of the horrible -traditional-cpp
   behavior, but it is unlikely that we ever will either. This allows us to
   start trying to use clang as a /usr/bin/cpp replacement and see what pieces
   of -traditional-cpp mode people actually care about.

Factor out the 64-bit specific bits into a helper function and add an
equivalent that loads the 32-bit sections. This allows using llvm-rtdyld on ARM.

Add a bone-simple utility to load a MachO object into memory, look for
a function (main) in it, and run that function directly. This will be used
as a test and development platform for MC-JIT work regarding symbol resolution,
dynamic lookup, etc..

For example, on 32-bit architecture, don't promote all uses of the IV
to 64-bits just because one use is a 64-bit cast.

Carefully written implementations of the 32-bit integer divide and modulus functions for ARM.  These are still using a naive digit-by-digit algorithm, but the core loop has been carefully written.

functions and initializers, just report the declarations present in
the module.

The motivation is to open the way for using the lazy module parsing,
which should speed up clients that just want a symbol list (nm, ar).

This is slightly less precise, but since both -strip-dead-prototypes
and -globaldce are part of the standard pipeline, this shouldn't
change the result for clang/dragonegg produced binaries.

Any decl in an IL file was also put there because a FE expected it
to be necessary, so this should not be a problem for "-O0 -emit-llvm".

As a sanity check, I have bootstrapped clang on linux and built
firefox on both linux and darwin. A clang bootstrap on darwin
with LTO fails with or without this patch because, ironically,
the linker doesn't like the combination of dead_strip and LTO
when building libLTO.so :-)
