Alexander Richardson c14879562f Unbreak *tf builtins for hexfloat (#82208)
This re-lands cc0065a7d082f0bd322a538cf62cfaef1c8f89f8 in a way that
keeps existing targets working.

---------

Original commit message:
#68132 ended up removing
__multc3 & __divtc3 from compiler-rt library builds that have
QUAD_PRECISION but not TF_MODE due to missing int128 support.
I added support for QUAD_PRECISION to use the native hex float long double representation.
