The tree wi:: decompose routine wasn't asserting that the requested
precision matched the tree's precision. This could make a difference
for unsigned trees that are exactly N HWIs wide and that have the upper
bit set, since we then need an extra zero HWI when extending it to wider
precisions (as for wi::to_widest).
This patch adds the assert and fixes the fallout shown by the testsuite.
Go seems to be unaffected.

ALL_REGS doesn't function as a union class of POINTER_REGS and FP_REGS
since it includes the CC register as well. REGNO_REG_CLASS (CC_REGNUM)
is NO_REGS, but of course NO_REGS rightly doesn't include CC_REGNUM.
Adding a union class for POINTER+FP allows the RA to use it as the
preferred or alternative class of a pseudo. It also works as a
union class of GENERAL+FP for modes that aren't allowed in SP.
This is also needed for the SVE port, which adds predicate registers
to the mix.
