8b14625cc3 Make all the PCM plugins ops structure constant.
This ensures they are emitted in .data.rel.ro rather than .data.rel,
which should make a nice difference when using prelink.

8ed98db259 Make some static tables and strings constants.
By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.

The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

for that condition.
