remove the allocVector builtin
...
It's not needed anymore, because the "FixedArray" experimental feature is replaced by inline-arrays.

SimplifyBuiltin: support metatype and function types when optimizing Builtin.sizeof/alignof/strideof/destroyArray
...
Get the maximally abstracted lowered type instead of bailing if the ast type isn't equal to the lowered SIL type.

SIL: add CanonicalType.canBeClass
...
And move the implementation of `SIL.Type.canBeClass` to the AST Type. The SIL Type just calls the AST Type implementation.
Also rename `SIL.Type.canonicalASTType` -> `SIL.Type.astType`.

SIL: Let SubstitutionMap.replacementTypes return AST types rather than optional SIL types.
...
This is what the C++ SubstitutionMap does. One has to use `Type.loweredType` to get from the AST type to the SIL type.

SimplifyBuiltin: fix a wrong constant folding of the is_same_metatype builtin for function types
...
We need to compare the not lowered types, because function types may differ in their original version but are equal in the lowered version, e.g.
```
((Int, Int) -> ())
(((Int, Int)) -> ())
```
Fixes a miscompile

SIL: rename Type.instanceTypeOfMetatype -> Type.loweredInstanceTypeOfMetatype

The same for SILType
It needs to be made clear that this is not the "original", but the lowered SIL type.

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.

SIL: add a dependency token operand to global_addr
...
Optionally, the dependency to the initialization of the global can be specified with a dependency token `depends_on <token>`.
This is usually a `builtin "once"` which calls the initializer for the global variable.
