re PR c/83801 ([avr] String constant in __flash not put into .progmem)
PR c/83801
* c-tree.h (decl_constant_value_1): Add a bool argument.
* c-typeck.c (decl_constant_value_1): Add IN_INIT argument, allow
returning a CONSTRUCTOR if it is true. Use error_operand_p.
(decl_constant_value): Adjust caller.
* c-fold.c (c_fully_fold_internal): If in_init, pass true to
decl_constant_value_1 as IN_INIT. Otherwise, punt if
decl_constant_value returns initializer that has BLKmode or
array type.
(c_fully_fold_internal) <case COMPONENT_REF>: Fold if !lval.
* gcc.dg/pr83801.c: New test.
