Richard Henderson said [1] that these macros hiding the usage of *env "are evil". This patch series remove them and substitute with an explicit usage of *env by using registerfields API. Patch 20 (target/ppc: Add unused msr bits FIELDs) declares unused FIELDs, the same that were removed in patch 02 (target/ppc: Remove unused msr_* macros). I did that to keep the changes consistent with what was already present before. Patch 21 (target/ppc: Change MSR_* to follow POWER ISA numbering convention) changes the MSR_* bit number to match POWER ISA by adding a new macro to 'invert' the ordering.
