commit 2332d766f1fa0ca75eabb93b9b7cbf01df87b184

    RISC-V/testsuite/pr111466.c: update test and expected output
    
    Update the test to potentially generate two SEXT.W instructions: one for
    incoming function arg, other for function return.
    
    But after commit 8eb9cdd14218
    ("expr: don't clear SUBREG_PROMOTED_VAR_P flag for a promoted subreg")
    the test is not supposed to generate either of them so fix the expected
    assembler output which was errorneously introduced by commit above.
    
    gcc/testsuite/ChangeLog:
            * gcc.target/riscv/pr111466.c (foo2): Change return to unsigned
            int as that will potentially generate two SEXT.W instructions.
            dg-final: Change to scan-assembler-not SEXT.W.

    (cherry picked from commit 9cad42786ca28461633d524bbb6480f388bfdc55)
