Compilation warnings introduced by https://github.com/JuliaLang/julia/pull/16654

[Scott Jones]

@Yuyichao's merge of #16654 has introduced a couple of warnings.

/j/julia/src/gc-debug.c:475:22: warning: unused function 'jl_ns2ms' [-Wunused-function]

STATIC_INLINE double jl_ns2ms(int64_t t)

                     ^

/j/julia/src/gc-debug.c:480:22: warning: unused function 'jl_ns2s' [-Wunused-function]

STATIC_INLINE double jl_ns2s(int64_t t)

 

This would be fixed by simple moving line 485 to just before line 475.

Thanks to Jameson Nash for fixing this (and the other one!)
