Reduce contention on the Attributes lock by using atomic operations for reference counting rather than locking.

when trying to run opt in parallel.  This lets parallel opt crunch 403.gcc in about a third
of the time.

Privatize the ValueHandle global map.  Because this is used so heavily throughout the code base, locking all accesses to
it is not practical performance-wise.

need TypePrinting despite being a subclass of Constant. This fixes
compile-time problems especially visible on 403.gcc when -asm-verbose is
enabled.

WriteAsOperand in more places.

Now that more things are using WriteAsOperand, its behavior of
constructing a TypePrinting object and populating it with strings for all
the numbered types in the Module on each call is a significant bottleneck.
Fancier solutions could be pursued here, but for now, just bypass the
TypePrinting overhead in obvious cases.

This is vaguely consistent with LLVM's own source code, but more
importantly it lets more lines stay within 80 columns.

interesting to print the number in a comment. Numbered instructions
don't need their number in a comment either.

Also, tidy up newline printing.

and unnamed numbered global variables as "@0 = global ...". Extend the
AsmParser to recognize these forms.
