  [CIR] Implement Statement Expressions (#153677)

Depends on #153625

This patch adds support for statement expressions. It also changes
emitCompoundStmt and emitCompoundStmtWithoutScope to accept an Address
that the optional result is written to. This allows the creation of the
alloca ahead of the creation of the scope which saves us from hoisting
the alloca to its parent scope.
