[ABI] Accumulated API/ABI changes

* Renamed all eq() methods to equals() (consistency) (ABI)
  * Reorganized some X86 instructions in X86 database
  * Properly detect RISC-V CPU at compile time (Environment)
  * Removed CallConvId::kNone in favor of defaulting to kCDecl (ABI)
  * CallConvId::kHost is now alias to CallConvId::kCDecl (ABI)
  * Added FloatABI to Environment to disginguish between softfloat
    and hardfloat
  * Added more AArch64 CPU features and their detection (ABI)
  * Because of CallConvId changes it's now possible to run
    compiler tests on 32-bit ARM (fixes a bug in test cases)
  * Added QEMU to CI build matrix to test different architectures
