Subject: [PATCH] Fix lval extension for compressed assignment in constant
 function.

The type of extension (zero/sign) is determined by the expression
type, not the operand type, so we need to cast to the expression
type before extending the value.

(cherry picked from commit 241b6723e530d204619b0b73f78a4038af3667f3)
