    arm: Fix CASE_VECTOR_SHORTEN_MODE for thumb2.

    The CASE_VECTOR_SHORTEN_MODE query is missing some equals signs
    which causes suboptimal codegen due to missed optimisation
    opportunities. This patch also adds a test for thumb2
    switch statements as none exist currently.

    gcc/ChangeLog:
            PR target/115353
            * config/arm/arm.h (enum arm_auto_incmodes):
            Correct CASE_VECTOR_SHORTEN_MODE query.

    gcc/testsuite/ChangeLog:

            * gcc.target/arm/thumb2-switchstatement.c: New test.
