re PR rtl-optimization/66152 (suboptimal load bytes to stack)
PR rtl-optimization/66152
* builtins.h (c_readstr): Declare.
* builtins.c (c_readstr): Remove forward declaration. Add
null_terminated_p argument, if false, read all bytes from the
string instead of stopping after '\0'.
* expr.c (string_cst_read_str): New function.
(store_expr): Use string_cst_read_str instead of
builtin_strncpy_read_str. Try to store by pieces the whole
exp_len first, and only if that fails, split it up into
store by pieces followed by clear_storage. Formatting fix.
* gcc.target/i386/pr66152.c: New test.
