Fix output_constructor_bitfield handling of wide bitfields (PR89037)
The testcase was failing because we were trying to access
TREE_INT_CST_ELT (x, 1) of a 128-bit integer that was small enough
to need only a single element.

* varasm.c (output_constructor_bitfield): Use wi::extract_uhwi
instead of accessing TREE_INT_CST_ELT directly.
