Hi,

this series implements the insns reported in [1], as well as ftou. Also I fixed
two bugs in the insert insn which I came across during testing.

Cheers,
Bastian

[1] https://gitlab.com/qemu-project/qemu/-/issues/1667

v1 -> v2:
    - Removed useless deposits in crc_div()
    - Replaced final deposit() with extract() in helper_crcn()
    - Add trap if not feature_162 (CRCN)
    - Removed special case for NAN input (FTOU)
    - Clarified why we need arg < 0.0 special case (FTOU, FTOUZ)
    - Removed special case for f_arg being infinity (ftohp, hptof)
    - Clarified, why we need a special case for arg being NAN (ftohp, hptof)
