RFR: 8345609: [C1] LIR Operations with one input should be implemented as LIR_Op1 [v2]

[Martin Doerr]

> Change `lir_sqrt`, `lir_abs`, `lir_neg`, `lir_f2hf`, `lir_hf2f` to use `LIR_Op1`. Extend `LIR_Op1` to support one temp register operand.
> Also see JBS issue.
> 
> Remove `lir_tan` and `lir_log10` which are unused (dead and incomplete code). They should have been removed with or after https://github.com/openjdk/jdk/commit/ad79a5ae65d24861ead3ae96cf148c8bc0f02736 and the corresponding changes on other platforms.
