If we've pushed registers onto the stack, but aren't adjusting the stack pointer
(i.e., there are no local variables and stuff), we still need to output FDE
information for the pushed registers.

Remove the API for creating ConstantExprs with the nsw, nuw, inbounds,
and exact flags. Because ConstantExprs are uniqued, creating an
expression with this flag causes all expressions with the same operands
to have the same flag, which may not be safe. Add, sub, mul, and sdiv
ConstantExprs are usually folded anyway, so the main interesting flag
here is inbounds, and the constant folder already knows how to set the
inbounds flag automatically in most cases, so there isn't an urgent need
for the API support.

This can be reconsidered in the future, but for now just removing these
API bits eliminates a source of potential trouble with little downside.

Make ImmutableMap/ImmutableSet quicker by only canonicalizing the tree after an
Add or Remove operation complete, and not while building the intermediate tree.
This trades a little bit more memory usage for less accesses to the FoldingSet.  On a benchmark for the clang static analyzer, this shaves off another 13% of execution time when using field/array sensitivity.

Overhaul the TwoAddressInstructionPass to simplify the logic, especially
for the complicated case where one register is tied to multiple destinations.
This avoids the extra scan of instruction operands that was introduced by
my recent change.  I also pulled some code out into a separate
TryInstructionTransform method, added more comments, and renamed some
variables.

Besides all those changes, this takes care of a FIXME in the code regarding
an assumption about there being a single tied use of a register when
converting to a 3-address form.  I'm not aware of cases where that assumption
is violated, but the code now only attempts to transform an instruction,
either by commuting its operands or by converting to a 3-address form,
for the simple case where there is a single pair of tied operands.

Added opaque 32-, 48-, and 80-bit memory operand types to the X86
instruction tables to support segmented addressing (and other objects
of obscure type).
Modified the X86 assembly printers to handle these new operand types.
Added JMP and CALL instructions that use segmented addresses.

Changed profiling-tool-chain.ll test to use optimal-edge-profiling instead of
edge-profiling, this is more useful since the loading of the

The edge-profiling is tested in edge-profiling.ll where only the
instrumentation is tested.
