[PATCH 0/3] target/arm: Implement v8.3-RCPC and v8.4-RCPC |

This patchset implements the Arm architectural features
ARMv8.3-RCPC and ARMv8.4-RCPC. These provide a handful of
new load and store instructions which have "LoadAcquirePC"
semantics. These are slightly weaker than standard
"LoadAcquire", so we choose to implement them in QEMU as
LoadAcquire.
Patch 1 is a trivial fix to the PMU isar function which
I managed to cut-n-paste with the wrong FIELD_EX* macro.
I've tested these using risu against an Arm AEM FVP model:
this doesn't do anything to test the memory barrier semantics
but does work as a check that the decode is correct and
that the various signed/unsigned/extend/etc operations
are being done correctly.
thanks
