[release-branch.go1.27] database/sql: fix closingMutex writer coordination

Lock loads the mutex state and first tries to acquire it. If a reader
acquires and releases the mutex after that load, Lock could use the stale
value to change state from 0 to 1 and then wait. With no active reader,
nothing would wake the writer.

After a failed acquire from an unlocked state, reload the state before
setting the writer-waiting bit. This ensures Lock only waits for readers
when a future RUnlock is guaranteed to notify it.

Fixes #81151

[release-branch.go1.27] cmd/compile: fix incorrect qualifying generic methods with alias receiver

Generic method formatting relies on the underlying defined type of the
receiver. However, when determining whether to format a pointer
receiver, the compiler incorrectly checked the alias type instead of the
unaliased defined type, resulting in an incorrect qualify identifier.

Fix this by unwrapping the receiver alias type before evaluating the
pointer formatting logic.

Fixes #81195
