single code path. Use atomic loads and stores where necessary. Load and
store anything of the appropriate size and alignment with primitive
operations instead of going through the call.

SplitKit will soon need two copies of these data structures, and the
algorithms will also be useful when LiveIntervalAnalysis becomes
independent of LiveVariables.

already provided. This required a little bit of clean-up in the way
that VerifyDiagnosticsClient managed ownership of its underlying
"primary" client, because now it will no longer always take ownership.

(running under any uid) if lldb is being run as root. It might be
better to handle this up at the ProcessInstanceInfoMatch class with
its m_match_all_users ivar instead of down here...

o Rename from OptionGroupWatchpoint::WatchMode to OptionGroupWatchpoint::WatchType,
and CommandArgumentType::eArgTypeWatchMode to CommandArgumentType::eArgTypeWatchType.
Update the sources to reflect the change.
o Add a CreateWatchpointLocation() method to Target class, which is currently not implmeneted
(returns an empty WatchpointLocationSP object). Add logic to CommandObjectFrame::Execute()
to exercise the added API for creating a watchpoint location.

but there is a corresponding umbrella header in a framework, build the
module on-the-fly so it can be immediately loaded at the import
statement. This is very much proof-of-concept code, with details to be
fleshed out over time.

Address ranges are now split up into two different tables:
- one in DWARFDebugInfo that is compile unit specific
- one in each DWARFCompileUnit that has exact function DIE offsets
This helps keep the size of the aranges down since the main table will get
uniqued and sorted and have consecutive ranges merged. We then only parse the
compile unit one on demand once we have determined that a compile unit contains
the address in question. We also now use the .debug_aranges section if there
is one instead of always indexing the DWARF manually.
NameToDIE now uses a UniqueCStringMap<dw_offset> map instead of a std::map.
std::map is very bulky as each node has 3 pointers and the key and value types.
This gets our NameToDIE entry down to 12 bytes each instead of 48 which saves
us a lot of memory when we have very large DWARF.
DWARFDebugAranges now has a smaller footprint for each range it contains to
save on memory.

a DeclRefExpr, MemberExpr, etc. with a CastExpr if it is ImplicitCast,
since the implicit cast is the one that is invisible in source code.

Splitting a landing pad takes considerable care because of PHIs and other
nasties. The problem is that the jump table needs to jump to the landing pad
block. However, the landing pad block can be jumped to only by an invoke
instruction. So we clone the landingpad instruction into its own basic block,
have the invoke jump to there. The landingpad instruction's basic block's
successor is now the target for the jump table.
But because of PHI nodes, we need to create another basic block for the jump
table to jump to. This is definitely a hack, because the values for the PHI
nodes may not be defined on the edge from the jump table. But that's okay,
because the jump table is simply a construct to mimic what is happening in the
CFG. So the values are mysteriously there, even though there is no value for the
PHI from the jump table's edge (hence calling this a hack).

where the compiler will look for module files. Eliminates the
egregious hack where we looked into the header search paths for
modules.

No tests; these changes aren't really interesting in the sense that the logic is the same for volatile and atomic.
I believe this completes all of the changes necessary for the optimizer to handle loads and stores correctly. I'm going to try and come up with some additional testing, though.

However with this fix it does now.
Basically the operand order for the x86 target specific node
is not the same as the instruction, but since the intrinsic need that
specific order at the instruction definition, just change the order
during legalization. Also, there were some wrong invertions of condition
codes, such as GE => LE, GT => LT, fix that too. Fix PR10907.
