Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20140310' into staging
target-arm queue:
 * implement WFE as yield (improves performance with emulated SMP)
 * fixes to avoid undefined behaviour shifting left into sign bit
 * libvixl format string fixes for 32 bit hosts
 * fix build error when intptr_t and tcg_target_long are different
   sizes (eg x32)
 * implement PMCCNTR register
 * fix incorrect setting of E bit in CPSR (broke booting under
   KVM on ARM)
