Gustavo Romero a72c71b77d target/ppc: Integrate icount to purr, vtb, and tbu40 
Currently if option '-icount auto' is passed to the QEMU TCG to enable
counting instructions the VM crashes with the following error report when
Linux runs on it:

qemu-system-ppc64: Bad icount read

This happens because read/write access to the SPRs PURR, VTB, and TBU40
is not integrated to the icount framework.

This commit fixes that issue by making the read/write access of these
SPRs aware of icount framework, adding the proper gen_io_start() calls
before calling the helpers to load/store these SPRs in TCG and ensuring
that the associated TBs end immediately after, accordingly to what's in
docs/devel/tcg-icount.rst.
