target-arm: Don't decode old cp15 WFI instructions on v7 cores

In v7 of the ARM architecture, WFI (wait for interrupt) is a first-class
instruction, but in previous versions this functionality was provided
via a cp15 coprocessor register. Add correct feature checks to the...

target-arm: Introduce float64_256 and float64_512 constants.

These two constants will be used by helper functions such as recpe_f32
and rsqrte_f32.

target-arm: Fix shift by immediate and narrow where src, dest overlap

For Neon shifts by immediate and narrow, correctly handle the case
where the source registers and the destination registers overlap
(the second pass should use the original register contents, not the...

target-arm: Refactor to pull narrowing decode into separate function

Pull the code which decodes narrowing operations as being either
signed/unsigned saturate or plain out into its own function.

target-arm: Fix signed VQRSHL by large shift counts

Handle the case of signed VQRSHL by a shift count of the width of the
data type or larger, which must be special cased in the qrshl_s*
helper functions.
