testsuite: Verify r0-r3 are extended with CMSE
Add regression test to the existing zero/sign extend tests for CMSE to
verify that r0, r1, r2 and r3 are properly extended, not just r0.
boolCharShortEnumSecureFunc test is done using -O0 to ensure the
instructions are in a predictable order.
gcc/testsuite/ChangeLog:
* gcc.target/arm/cmse/extend-param.c: Add regression test. Add
-fshort-enums.
* gcc.target/arm/cmse/extend-return.c: Add -fshort-enums option.
