commit ce71cb796527be4ac326155aa7f348cabbe89009

Fortran: Fixes and additional tests for shape/ubound/size [PR94070]
This patch reimplements the SHAPE intrinsic to be inlined similarly to
LBOUND and UBOUND, instead of as a library call, to avoid an
unnecessary array copy. Various bugs are also fixed.
gcc/fortran/
PR fortran/94070
* expr.c (gfc_simplify_expr): Handle GFC_ISYM_SHAPE along with
GFC_ISYM_LBOUND and GFC_ISYM_UBOUND.
* trans-array.c (gfc_conv_ss_startstride): Likewise.
(set_loop_bounds): Likewise.
* trans-intrinsic.c (gfc_trans_intrinsic_bound): Extend to
handle SHAPE. Correct logic for zero-size special cases and
detecting assumed-rank arrays associated with an assumed-size
argument.
(gfc_conv_intrinsic_shape): Deleted.
(gfc_conv_intrinsic_function): Handle GFC_ISYM_SHAPE like
GFC_ISYM_LBOUND and GFC_ISYM_UBOUND.
(gfc_add_intrinsic_ss_code): Likewise.
(gfc_walk_intrinsic_bound): Likewise.
