717880e844 PerformanceDiagnostics: avoid false meta-data alarms for non-loadable types 
Non-loadable types don't necessarily need metadata, for example, structs with `@_rawLayout`

5dc3cf1296 [LifetimeCompletion] Removed "with leaks" mode. 
Now that the two known issues which resulted in invalid SIL being
provided to lifetime completion have been addressed, tighten up the
completion done on the availability boundary not to allow leaks.

84da0ed4c5 [LifetimeCompletion] Add extend_lifetimes. 
The new instructions are inserted after every "user" (according to
InteriorLiveness' SSAPrunedLiveness instance) outside the linear
liveness boundary.

81fa65772f [OwnershipLiveness] End at extend_lifetime. 
When visiting consumes, also visit `extend_lifetime` instructions.
These instructions are not lifetime ending, but together with the
consumes, they enclose the users of a value.

Add a flag to LinearLiveness to control whether these instructions are
added so that the verifier can use verify that all such instructions
appear outside the linear lifetime boundary (not including them).

2a5d07522d [SIL] Add extend_lifetime instruction. 
It indicates that the value's lifetime continues to at least this point.
The boundary formed by all consuming uses together with these
instructions will encompass all uses of the value.

77d26e1eff [NFC] LifetimeCompletion: Rename helper fn.

ends" are.

9d7db52bed [NFC] PrunedLiveness: Tweaked enum wrapper. 
Clarify methods.  Unfortunately, without other changes I haven't
identified, the `enum class` can't be made an `enum` for ideal usage.

1d8ea84fa3 [region-isolation] When determining isolation of a full apply site... use the isolated parameter, not self. 
This was ok in the small since most of the time we were processing a self
parameter as isolated... but that isn't always true...

4ecfc96578 [SIL][PackageCMO] Allow optimizing [serialized_for_pkg] functions during SIL 
inlining, generic/closure specialization, and devirtualization optimization passes.

SILFunction::canBeInlinedIntoCaller now exlicitly requires a caller's SerializedKind_t arg.
isAnySerialized() is added as a convenience function that checks if [serialized] or [serialized_for_pkg].

5ccc4cd394 SIL function can be serialized with different kinds: [serialized] or 
[serialized_for_package] if Package CMO is enabled. The latter kind
allows a function to be serialized even if it contains loadable types,
if Package CMO is enabled. Renamed IsSerialized_t as SerializedKind_t.

The tri-state serialization kind requires validating inlinability
depending on the serialization kinds of callee vs caller; e.g. if the
callee is [serialized_for_package], the caller must be _not_ [serialized].
Renamed `hasValidLinkageForFragileInline` as `canBeInlinedIntoCaller`
that takes in its caller's SerializedKind as an argument. Another argument
`assumeFragileCaller` is also added to ensure that the calle sites of
this function know the caller is serialized unless it's called for SIL
inlining optimization passes.

The [serialized_for_package] attribute is allowed for SIL function, global var,
v-table, and witness-table.

closure-spec optimization pass cannot solely support OSSA instructions.
