match.pd: Only merge truncation with conversion for -fno-signed-zeros

This optimisation does not honour signed zeros, so should not be
enabled except with -fno-signed-zeros.

gcc/ChangeLog:

* match.pd: Fix truncation pattern for -fno-signed-zeroes

gcc/testsuite/ChangeLog:

* gcc.target/aarch64/no_merge_trunc_signed_zero.c: New test.
