ae797d43e9 [region-isolation] Propagate through the whole source operand instead of just the representative of the source value when constructing assign and merge.
This will let me know the exact source operand used instead of the source value
representative. This will ensure that the name associated with the diagnostic is
not of the representative value, but the actual value that was the source of the
assign.

This is an NFCI commit that is an algebraic refactor.

27a8852290 MoveOnlyAddressChecker: More robust checking for consume-during-borrow.
- While an opaque borrow access occurs to part of a value, the entire scope of
  the access needs to be treated as a liveness range, so add the `EndAccess`es
  to the liveness range.
- The SIL verifier may crash the compiler on SILGen-generated code when the
  developer's source contains consume-during-borrow code patterns. Allow
  `load_borrow` instructions to be marked `[unchecked]`, which suppresses
  verifier checks until the move checker runs and gets a chance to properly
  diagnose these errors.

Fixes rdar://124360175.

0be63d0422 [DebugInfo] Return complete variable info from getVarInfo by default
getVarInfo() now always returns a variable with a location and scope.
To opt out of this change, getVarInfo(false) returns an incomplete variable.
This can be used to work around bugs, but should only really be used for
printing.

The complete var info will also contain the type, except for debug_values,
as its type depends on another instruction, which may be inconsistent if
called mid-pass.

All locations in debug variables are now also stripped of flags, to avoid
issues when comparing or hashing debug variables.

6136183c33 [DebugInfo] Fix loss of VarDecl in debug values for salvaged stores
When a store is salvaged, its debug_value will have two locations:
the location of the store, attached to the debug_value instruction,
and the location of the variable, attached to the SILDebugVariable.

The getDecl function was using the location of the store, instead
of the location of the variable, and so was returning nullptr.

0a282c044f Unify all of the task-creation builtins coming out of SILGen.
We've been building up this exponential explosion of task-creation
builtins because it's not currently possible to overload builtins.
As long as all of the operands are scalar, though, it's pretty easy
to peephole optional injections in IRGen, which means we can at
least just use a single builtin in SIL and then break it apart in
IRGen to decide which options to set.

I also eliminated the metadata argument, which can easily be recreated
from the substitutions.  I also added proper verification for the builtin,
which required (1) getting `@Sendable` right more consistently and (2)
updating a bunch of tests checking for things that are not actually
valid, like passing a function that returns an Int directly.

3488cd364f SIL: remove instruction leaks checking
It's not thread safe and can cause false alarms in case multiple modules exist in different threads. E.g. when building swiftmodules from interfaces.
The leaking check is not important anymore because the builder APIs enforce that instructions are not leaking.
I.e. it's not possible to create an instruction without inserting it into a basic block. Also, it's not possible to remove an instruction from a block without deleting it.
