In RISC-V we have multiple extensions, that can be
used to accelerate processing.
The known extensions are defined in riscv_arch.def.
From that file test functions of the following
form are generated: RISCV_HAS_$ext().
In recent commits new ways to define the availability
of these test macros have been defined. E.g.:
#define RV32I_ZKND_ZKNE_CAPABLE \
(RISCV_HAS_ZKND() && RISCV_HAS_ZKNE())
[...]
#define RV64I_ZKND_ZKNE_CAPABLE \
(RISCV_HAS_ZKND() && RISCV_HAS_ZKNE())
This leaves us with two different APIs to test capabilities.
Further, creating the same macros for RV32 and RV64 results
in duplicated code (see example above).
This inconsistent situation makes it hard to integrate
further code. So let's clean this up with the following steps:
* Replace RV32I_* and RV64I_* macros by RICSV_HAS_* macros
* Move all test macros into riscv_arch.h
* Use "AND" and "OR" to combine tests with more than one extension
* Rename include files for accelerated processing (remove extension
postfix).
We end up with compile time tests for RV32/RV64 and run-time tests
for available extensions. Adding new routines (e.g. for vector crypto
instructions) should be straightforward.
Testing showed no regressions.
