[COMMITTED] Fix PR aarch64/104474: ICE with vector float initializers and non-consts.
The problem here is that the aarch64 back-end was placing const0_rtx into the constant vector RTL even if the mode was a floating point mode. The fix is instead to use CONST0_RTX and pass the mode to select the correct zero (either const_int or const_double). Committed as obvious after a bootstrap/test on aarch64-linux-gnu with no regressions. PR target/104474 gcc/ChangeLog: * config/aarch64/aarch64.cc (aarch64_sve_expand_vector_init_handle_trailing_constants): Use CONST0_RTX instead of const0_rtx for the non-constant elements. gcc/testsuite/ChangeLog: * gcc.target/aarch64/sve/pr104474-1.c: New test. * gcc.target/aarch64/sve/pr104474-2.c: New test. * gcc.target/aarch64/sve/pr104474-3.c: New test.
