objects in llvm.used (thanks Anton).  Makes visible
the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

Move SLEB/ULEB size calculation routines from AsmPrinter to TargetAsmInfo. This makes JIT asmprinter-free.

Reduce heap trashing due to std::string construction / concatenation via caching of section flags string representations

It's not legal to output a GV in a coalesced section if it's used in an ARM PIC relative constantpool.

moves in order to get correct debug info.  Since
I can't imagine how any target could possibly
be any different, I've just stripped out the
option: now all the world's like Darwin!

debug information is being output, because it's leet!

Start refactoring of asmprinters: provide a TAI hook, which will select a 'section kind' for a global.

assembler names of string constants look like.

on x86-64 linux.  This causes no regressions on
32 bit linux and 32 bit ppc.  More tests pass
on 64 bit ppc with no regressions.  I didn't
turn on eh on 64 bit linux because the intrinsics
needed to compile the eh runtime aren't done
yet.  But if you turn it on and link with the
mainline runtime then eh seems to work fine
on x86-64 linux with this patch.  Thanks to
Dale for testing.  The main point of the patch
is that if you output that some object is
encoded using 4 bytes you had better not output
8 bytes for it: the patch makes everything
consistent.

the code being generated does not require an executable stack.

Also, add target-specific code to make use of this on Linux
on x86.

providing a misleading facility. It's used once in the MIPS backend
and hardcoded as "\t.globl\t" everywhere else.
