lower-bitint: Fix up VIEW_CONVERT_EXPR handling [PR113408]
Unlike NOP_EXPR/CONVERT_EXPR which are GIMPLE_UNARY_RHS, VIEW_CONVERT_EXPR
is GIMPLE_SINGLE_RHS and so gimple_assign_rhs1 contains the operand wrapped
in VIEW_CONVERT_EXPR tree.
So, to handle it like other casts we need to look through it.

* gimple-lower-bitint.cc (bitint_large_huge::handle_stmt): For
VIEW_CONVERT_EXPR, pass TREE_OPERAND (rhs1, 0) rather than rhs1
to handle_cast.
* gcc.dg/bitint-71.c: New test.
