[PATCH][AArch64][obvious] Clean up parentheses and use GET_MODE_UNIT_BITSIZE in a couple of patterns

[Kyrill Tkachov]

Hi all,

The parentheses in these two patterns are a bit of a mess and we can remove 
them.
Do that. also, use '{' and '}' for the C code so that we can avoid escaping the 
strings
in the block.  Also, use GET_MODE_UNIT_BITSIZE directly instead of taking 
GET_MODE_UNIT_SIZE and
multiplying by BITS_PER_UNIT which is equivalent.

Bootstrapped and tested on aarch64.
Committing as obvious.

Thanks,
Kyrill

    * config/aarch64/aarch64-simd.md (aarch64_<sur>shll_n<mode>): Clean
    up parentheses.  Use GET_MODE_UNIT_BITSIZE.
    (aarch64_<sur>shll2_n<mode>): Likewise.
