Translators are no longer required to free tcg temporaries,
therefore there's no need to record temps for later freeing.
Replace the few uses with tcg_temp_new.

We should call decode_save_opc() for all relevant instructions which
can potentially generate a virtual instruction fault or a guest page
fault because generating transformed instruction upon guest page fault
expects opcode to be available. Without this, hypervisor will see
transformed instruction as zero in htinst CSR for guest MMIO emulation
which makes MMIO emulation in hypervisor slow and also breaks nested
virtualization.
Fixes: a9814e3e08 ("target/riscv: Minimize the calls to decode_save_opc")

The implementation in trans_{rvi,rvv,rvzfh}.c.inc accesses the shallow
copies (in DisasContext) of some of the elements available in the
RISCVCPUConfig structure. This commit redirects accesses to use the
cfg_ptr copied into DisasContext and removes the shallow copies.

Zfhmin extension is a subset of Zfh extension, consisting only of data
transfer and conversion instructions.
If enabled, only the following instructions from Zfh extension are
included:
* flh, fsh, fmv.x.h, fmv.h.x, fcvt.s.h, fcvt.h.s
* If D extension is present: fcvt.d.h, fcvt.h.d
