2021-10-29target/riscv: change the api for RVF/RVD fmin/fmaxChih-Min Chao
The sNaN propagation behavior has been changed since cd20cee7 in https://github.com/riscv/riscv-isa-manual. In Priv spec v1.10, RVF is v2.0. fmin.s and fmax.s are implemented with IEEE 754-2008 minNum and maxNum operations. In Priv spec v1.11, RVF is v2.2. fmin.s and fmax.s are amended to implement IEEE 754-2019 minimumNumber and maximumNumber operations. Therefore, to prevent the risk of having too many version variables. Instead of introducing an extra *fext_ver* variable, we tie RVF version to Priv version. Though it's not completely accurate but is close enough.

2021-10-29target/riscv: remove force HS exceptionJose Martins
There is no need to "force an hs exception" as the current privilege level, the state of the global ie and of the delegation registers should be enough to route the interrupt to the appropriate privilege level in riscv_cpu_do_interrupt. The is true for both asynchronous and synchronous exceptions, specifically, guest page faults which must be hardwired to zero hedeleg. As such the hs_force_except mechanism can be removed.

2021-10-29target/riscv: fix VS interrupts forwarding to HSJose Martins
VS interrupts (2, 6, 10) were not correctly forwarded to hs-mode when not delegated in hideleg (which was not being taken into account). This was mainly because hs level sie was not always considered enabled when it should. The spec states that "Interrupts for higher-privilege modes, y>x, are always globally enabled regardless of the setting of the global yIE bit for the higher-privilege mode." and also "For purposes of interrupt global enables, HS-mode is considered more privileged than VS-mode, and VS-mode is considered more privileged than VU-mode". Also, vs-level interrupts were not being taken into account unless V=1, but should be unless delegated. Finally, there is no need for a special case for to handle vs interrupts as the current privilege level, the state of the global ie and of the delegation registers should be enough to route all interrupts to the appropriate privilege level in riscv_cpu_do_interrupt.
