RFR: 8347627: Compiler replay tests are failing after JDK-8346990

[David Holmes]

The `%#zx` format specifier only prepends `0x` to non-zero values but we need it for all, so switch to manual `0x%zx`. I claim this as a trivial (and urgent) fix.

The only other use of this is in a test where it is fine.

Testing:
 - compiler replay tests now pass
 - tiers 1-3 (sanity)

Thanks
