tree-optimization/103759: Use sizetype everywhere for object sizes
Since all computations in tree-object-size are now done in sizetype and
not HOST_WIDE_INT, comparisons with HOST_WIDE_INT based unknown and
initval would be incorrect. Instead, use the sizetype trees directly to
generate and evaluate initval and unknown size values.
gcc/ChangeLog:
PR tree-optimization/103759
* tree-object-size.c (unknown, initval): Remove functions.
(size_unknown, size_initval, size_unknown_p): Operate directly
on trees.
