TARGET_FPRND should be on for everything ISA 2.04 and later, and
TARGET_VSX implies ISA 2.06 or later; but it is possible to disable
TARGET_FPRND (separately via -mno-fprnd, but also implicitly)
currently, and then things fall down. This patch makes things not
fall down.

The instruction set first appeared with Westmere, but not all processors
in that and the next few generations have the instructions. According to
Wikipedia[1], the first generation in which all SKUs have AES
instructions are Skylake and Goldmont. I can't find any Skylake,
Kabylake, Kabylake-R or Cannon Lake currently listed at
https://ark.intel.com that says "Intel® AES New Instructions" "No".

On AArch64 we have integer modes larger than TImode, and while we can generate
moves for these they're not as efficient.
So instead make sure we limit the maximum we can copy to TImode. This means
copying a 16 byte struct will issue 1 TImode copy, which will be done using a
single STP as we expect but an CImode sized copy won't issue CImode operations.
I am also moving the residual code inside the if since smallest_mode_for_int may
trap if the mode doesn't exist. And the only time we know the mode to exist for
sure is when the condition of the if is true. This also saves repeated calls to
the iterator.
