Swift SIL: mark SIL object classes as immortal
...
This avoids ARC operations on those objects which improves compile time.

Swift SIL: speed up Operand.value
...
Instead of doing the type casts and/or conformance lookup on the swift side, do it on the C++ side.
It makes a significant performance difference because `Operand.value` is a time critical function

Swift SIL: invert Type.isNonTrivialOrContainsRawPointer to Type.isTrivialNonPointer
...
This is consistent with `Type.isTrivial`.
Also, introduce corresponding properties in `Value`: `hasTrivialType` and `hasTrivialNonPointerType`, because
1. It's less to type than `Type.isTrivial(in: function)` because `Value` knows in which function it is.
2. It fixes the corner case where value is an `Undef`, which has not parent function.

Swift SIL: add ProjectedValue.
...
A projected value consists of the original value and a projection path.
For example, if the `value` is of type `struct S { var x: Int }` and `path` is `s0`, then the projected value represents field `x` of the original value.
Also, use ProjectedValue instead of AccessStoragePath.

[cxx-interop][SwiftCompilerSources] Workaround for std::string crash on arm64 Linux
...
`std::string` constructor crashes when called from `SILBridging.cpp`, likely due to a miscompile. This is a workaround that fixes the crash.

[cxx-interop][SwiftCompilerSources] Fix conversion between std::string and Swift.String
...
This fixes a dangling pointer issue when creating a `Swift.String` from `std::string`.
Also fixes a warning:
```
warning: variable 's' was never mutated; consider changing to 'let' constant
var s = SILBasicBlock_debugDescription(bridged)
~~~ ^
let
```
