interp: Potential linker buildfix.
...
Just in case it's thinking there's a definition to link, should use static.

Better to use S000, etc. as that's more clear throughout.

Add back our older VFPU approximations, as fallbacks if files are missing.
...
PR #16984 added more accurate versions of these functions, but they require
large lookup tables stored in assets/.
If these files are missing, PPSSPP would simply crash, which isn't good.
We should probably try to warn the user somehow that these files are
missing, though...

macros to select the constant, although that's how the bits work.
