[PATCH] Minor documentation correction in aarch64-simd.md

[Indu Bhagat <indu dot bhagat at oracle dot com>]

In function minmax_replacement in tree-ssa-phiopt.c, MIN_EXPR/MAX_EXPR 
are substituted for when the following condition is false - (HONOR_NANS 
(type) || HONOR_SIGNED_ZEROS (type)). So for FP mode, this is false when 
_both_ of the following conditions are fulfilled : 1. flag_signed_zeros 
is zero and 2. flag_finite_math_only is set. So, the documentation in 
aarch64-simd.md is partially misleading. Here is a patch to correct 
that. Thanks

gcc/ChangeLog:

        * config/aarch64/aarch64-simd.md: correct flags text for 
MIN_EXPR replacement
