Handle POLY_INT_CSTs in declare_return_value
SVE allows variable-length vectors to be returned by value,
which tripped the assert in declare_return_variable.
2019-11-08 Richard Sandiford <richard.sandiford@arm.com>
gcc/
* tree-inline.c (declare_return_variable): Check for poly_int_tree_p
instead of INTEGER_CST.
gcc/testsuite/
* gcc.target/aarch64/sve/acle/general/inline_1.c: New test.
