Function calls and returns in Wasm are protected by Wasm runtime and there is no way to get or control return address.
…ures When SWIFT_COMPACT_ABSOLUTE_FUNCTION_POINTER is enabled, relative direct pointers whose pointees are functions will be turned into absolute pointer at compile-time.

I fixed the issues exposed with alloc-stack-hoisting for llvm.dbg.addr some time ago but didn't update this test. The test changes are b/c I did not fix this for llvm.dbg.declare resulting in us losing the variable "m" in certain situations. "k" the thing we care about is actually fine though.
The Requirement Machine has been enabled in 'verify' mode for a while, where we run both the GenericSignatureBuilder and Requirement Machine minimization algorithm and compare the results, with the GenericSignatureBuilder being used to emit diagnostics. Now, it's time to flip the flags to 'enabled' mode, where the GenericSignatureBuilder doesn't run at all, and the Requirement Machine emits diagnostics. This finally allows us to realize the correctness and performance gains from using the Requirement Machine. See https://forums.swift.org/t/the-requirement-machine-a-new-generics-implementation-based-on-term-rewriting/55601/9 for details.
