chacha20: extend ppc64le support to ppc64
...
This requires fixing an incorrect save of the counter. It is a word
value. It happens to work on LE because length is limited to u32.
Refactor the constant table to load correctly independent of byte
ordering.
Add byte order swapping where output needs converted to LE
ordering for storage.

...
- Adding PCALIGN before the loops
- Changing WORD directive with corresponding Vector Merge EVEN/ODD word instructions
- Replacing Branch Conditional (BC) with its extended mnemonic form BDNZ
- VPERMXOR instruction usage in place of VXOR instructions followed by
VRLW (rotate left) for cases of rotating in multiples of 8. This
replacements give performace improvement both in time and space of around 7%-8% as listed below
using benchstat tool.

Redundant bound checks on loading key and nonce as uint32s in newUnauthenticatedCipher
are eliminated.
In the main block loop, two changes were made:
1. Specialise the xor function to addXor, so the final block state variables don't need to be
separately incremented by the initial block state before XORing with the input block.
2. Change the loop condition to be bound by len(src) >=64 and len(dst) >= 64.
This eliminates all bound checks later in the load-xor-store stage.
As a result, src and dst are resliced in-place after each block.

Simply add the NonceSizeX constant, and accept 24 bytes nonces in
NewUnauthenticatedCipher. Based on draft-irtf-cfrg-xchacha-01 and
