Richard Purdie eb9809741c bitbake: runqueue: Rework process_possible_migrations() to improve performance

The looping over multiple changed hashes causes many calls to get_taskhash
and get_unihash which are potentially slow and then overwritten.

Instead, batch up all the tasks which have changed unihashes and then
do one big loop over the changed tasks rather than each in turn.

This makes worlds of difference to the performance graphs and should speed
up build where many tasks are being rehashed.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
