[IR] Allow fast math flags on fptrunc and fpext (#115894)
This consists of:
* Make these instructions part of FPMathOperator.
* Adjust bitcode/ir readers/writers to expect fast math flags on these
instructions.
* Make IRBuilder set the fast math flags on these instructions.
* Update langref and release notes.
* Update a bunch of tests. Some of these are due to InstCombineCasts
incorrectly adding fast math flags to fptrunc, which will be fixed in a
later patch.
