There are no values other than instructions that can use other values. BBArguments are
defs, not uses. This eliminates a bunch of casts in clients that use getUser().

Most alloc_stacks emitted by SILGen are temporaries and don't need to be preserved for debug info. It's only the ones that relate to local variables that we need to preserve. Fixes <rdar://problem/15272642>.

This will allow us to differentiate from regular inlined code (as in optimization inlining). Some passes(AllocBocToStack) and debug info would be allowed to be more aggressive/preserve less debug info with mandatory inlined code.

have it remove trivially dead operands of the dead instructions. On the
same testcase as last time, this eliminates a dead metatype, getting us to:
sil @_T1t1fFT_T_ : $@thin () -> () {
bb0:
%0 = tuple ()
%1 = alloc_stack $Int64 // var a // users: %7, %6
%2 = metatype $Int64.metatype
%3 = module #Builtin
%4 = integer_literal $Builtin.Int64, 1 // user: %5
%5 = struct $Int64 (%4 : $Builtin.Int64) // user: %6
store %5 to %1#1 : $*Int64
dealloc_stack %1#0 : $*@local_storage Int64
%8 = tuple () // user: %9
return %8 : $()
}

Make ApplyInst and PartialApplyInst directly take substitutions for generic functions instead of trying to stage out substitutions separately. The legacy reasons for doing this are gone.

This is was a very mechanical patch where I basically first renamed SILNodes.def
and then just kept fixing things until everything compiled, so even though it is
large patch I feel ok(ish) with committing it.
If anyone has any concerns/etc, please email me and I will revert in 1 second.
