[BUG]: debug labels are not hidden on GCC MIPS and LoongArch

[jf2048]

Describe the bug

When using gcc mips, gcc mips64, or gcc loongarch64, many debug labels beginning with $LVL $LBE and $LBB are present in the assembly output. This makes the output very hard to read. The problem is pronounced when using optimization flags as they add a lot more of these labels.

As a workaround, the labels can be disabled by manually passing the -g0 flag, but that also prevents the line colouring from working.

Steps to reproduce

1. Visit gcc.godbolt.org
2. Select any of the mips gcc, mips64 gcc or loongarch64 gcc compilers
3. Write a function with a few statements
4. Add the -O flag to compiler options
5. Look in the assembly output

Expected behavior

I expect the output to match the behavior of the other compilers, where these labels are hidden.
