Remove the -enable-ossa-modules option.
...
OSSA modules are enabled by default.
The compiler still accepts this option but it has no effect.

Update SimplifyCFG's replacement of phi with its incoming value
...
Previously we replaced phi with its incoming values when all incoming values were the same.
If the phi had itself as incoming value, it wasn't optimized. This PR handles such cases.

OSSA: simplify-cfg support for trivial block arguments.
...
Enable most simplify-cfg optimizations as long as the block arguments
have trivial types. Enable most simplify CFG unit tests cases.
This massively reduces the size of the CFG during OSSA passes.
Test cases that aren't supported in OSSA yet have been moved to a
separate test file for disabled OSSA tests,
Full simplify-cfg support is currently blocked on OSSA utilities which
I haven't checked in yet.

SIL optimizer: Add a new string optimization.
...
Optimizes String operations with constant operands.
Specifically:
* Replaces x.append(y) with x = y if x is empty.
* Removes x.append("")
* Replaces x.append(y) with x = x + y if x and y are constant strings.
* Replaces _typeName(T.self) with a constant string if T is statically known.
With this optimization it's possible to constant fold string interpolations, like "the \(Int.self) type" -> "the Int type"
This new pass runs on high-level SIL, where semantic calls are still in place.
