    testsuite: LoongArch: Remove from btrunc, ceil, and floor effective target 
allowlist
    
    Now that C default is C23, so we can no longer use LSX/LASX instructions
    for these operations as the standard disallows raising INEXACT
    exceptions.  So LoongArch is no longer suitable for these effective
    targets.
    
    Fix the test failures on gcc.dg/vect/vect-rounding-*.c.  For the old
    standards or -ffp-int-builtin-inexact we already provide test coverage
    with gcc.target/loongarch/vect-ftint.c.
    
    gcc/testsuite/ChangeLog:
    
            * lib/target-supports.exp
            (check_effective_target_vect_call_btrunc): Drop LoongArch.
            (check_effective_target_vect_call_btruncf): Likewise.
            (check_effective_target_vect_call_ceil): Likewise.
            (check_effective_target_vect_call_ceilf): Likewise.
            (check_effective_target_vect_call_floor): Likewise.
            (check_effective_target_vect_call_floorf): Likewise.
            (check_effective_target_vect_call_lfloor): Likewise.
            (check_effective_target_vect_call_lfloorf): Likewise.
