[PATCH] aarch64: Fix narrowing warning in aarch64_detect_vector_stmt_subtype

[Andrew Pinski]

There is a narrowing warning in aarch64_detect_vector_stmt_subtype
about gather_load_x32_cost and gather_load_x64_cost converting from int to 
unsigned.
These fields are always unsigned and even the constructor for sve_vec_cost takes
an unsigned. So let's just move the fields over to unsigned.

Build and tested for aarch64-linux-gnu.

gcc/ChangeLog:

        * config/aarch64/aarch64-protos.h (struct sve_vec_cost): Change 
gather_load_x32_cost
        and gather_load_x64_cost fields to unsigned.
