object, the timer it creates was not being deleted.  Since the
timer belonged to a static timer group, the timer group would
be destroyed on shutdown, and would notice and complain that
not all timers it contained were destroyed.

more efficient SmallPtrSet<MCSymbol*>.  This eliminates string
craziness and fixes CodeGen/X86/darwin-quote.ll with the new asmprinter.

Codegen is producing stubs in a nondeterminstic order, but it was doing
this before anyway.

Mangler::getNameWithPrefix.  In addition to avoiding some over
quoting, this also is more efficient because it uses smallvector
instead of std::string thrashing.

Follow up to 81494. When the folded reload is narrowed to a 32-bit load then change the destination register to a 32-bit one or add a sub-register index.

It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not
safe. This can happen we a subreg_to_reg 0 has been coalesced. One
exception is when the instruction that folds the load is a move, then we
can simply turn it into a 32-bit load from the stack slot.

how to fold notionally-out-of-bounds array getelementptr indices instead
of just doing these in lib/Analysis/ConstantFolding.cpp, because it can
be done in a fairly general way without TargetData, and because not all
constants are visited by lib/Analysis/ConstantFolding.cpp. This enables
more constant folding.

Also, set the "inbounds" flag when the getelementptr indices are
one-past-the-end.

is not the same as "inbounds") from GlobalOpt into a utility routine,

indices.
