[exclusivity] Add 'no_nested_conflict' flag to begin_access.
...
This statically guarantees that the access has no inner conflict within
its own scope.
IRGen will turn this into a "nontracking" access in which an
exclusivity check is performed for conflicts on an outer scope. However,
unlike normal accesses the runtime does not record the access, and the
access will not be checked for subsequent conflicts.
end_unpaired_access [no_nested_conflict] is not currently
supported. Making a begin_unpaired_access [no_nested_conflict] requires
deleting the corresponding end_unpaired_access. Future runtimes
could support this for verification by storing inline data in the
valud buffer. However, the runtime can never assume that a
[no_nested_conflict] begin_unpaired_access will have a corresponding
end_unpaired_access call without adding a new ExclusivityFlag for
that purpose.

Consistently use bitfield packing for different kinds of access markers for sanity sake.

[AST] Perf: Improve getDesugaredType() efficiency
...
Make getDesugaredType() as fast as possible for now. With the old way:
1) Switching over the sugared types turned into a frequently
mispredicted branch because the sugar in the type system is random
as far as the processor is concerned.
2) Storing the underlying/singlely-desugared type at different offsets
in memory adds more code bloat and misprediction.
Short of a major redesign to avoid pointer chasing, this is probably as
fast as the method will get.

[Basic] NFC: Inline bitfield cleanup
...
1) Remove SWIFT_INLINE_BITS boilerplate. Now that we're not using anonymous/transparent unions, we don't need the
SWIFT_BITFIELD_BITS macro.
2) Refine the the bitfield size check to better support templated bitfields.
3) Refine the SIL templated bitfields to not be prematurely "full".
