Issue of 64 bit kernel with A64FX

[lwang-astro]

I tried to create the 64 bit kernel, but I got an error.

input file: input.64
output file name: kernel_epep_64.hpp
conversion type: A64FX
error: unsupported vector type of B64 for A64FX

It seems a typo exist, in the input.64, there is no B64.
Here is the input.64:

EPI F64vec xi:pos
EPI F64 rsi:rs

EPJ F64vec xj:pos
EPJ F64 mj:mass
EPJ F64 rsj:rs

FORCE F64vec acc:acc
FORCE F64 pot:pot
FORCE S64 nnbi:nnb

F64 eps2
F64 rcut2
F64 G

rij = xi - xj
r2 = rij*rij + eps2
r2_cut = max(r2,rcut2)
r_inv  = rsqrt(r2_cut)
r2_inv = r_inv * r_inv
mr_inv  = mj * r_inv
mr3_inv = r2_inv * mr_inv
if r2 < max(rsi*rsi,rsj*rsj)
  nnbi  += 1
  endif
acc -= mr3_inv * rij
pot -= mr_inv

r2 < max(rsirsi,rsjrsj) generates the value with type B64.
I think there is a bug in translator of ARM SVE.
I will fix it.

Right now I am not in hurry to get the 64 bit version. I am planning to first add SPJ quad 32 bit kernel. If you can provide an example input for that (#4), I can try today.
