Revert the entire VLA series.

This reverts the following patch series, as they cause some regresssions.

vla: enable sizeof operator for indirection

	gdb/
	* eval.c (evaluate_subexp_for_sizeof) <UNOP_IND>: Create an indirect

commit b86138fb0484f42db6cb83abed1e3d0ad2ec4eac
vla: print "variable length" for unresolved dynamic bounds

	gdb/
	* c-typeprint.c (c_type_print_varspec_suffix): Added
	check for not yet resolved high bound. If unresolved, print
	"variable length" string to the console instead of random
	length.

commit e1969afbd454c09c3aad1990305715f70bc47c3c
vla: support for DW_AT_count

	gdb/
	* dwarf2read.c (read_subrange_type): Convert DW_AT_count to a dynamic
	property and store it as the high bound and flag the range accordingly.
	* gdbtypes.c (resolve_dynamic_bounds): If range is flagged as
	RANGE_UPPER_BOUND_IS_COUNT assign low + high - 1 as the new high bound.
	* gdbtypes.h (enum range_flags): New enum.
	(struct range_bounds): Add flags member.

commit 92b09522dc5a93ba4bda3c1c0b3c58264e357c8a
vla: resolve dynamic bounds if value contents is a constant byte-sequence

	gdb/
	* findvar.c (default_read_var_value): Resolve dynamic bounds if location
	points to a constant blob.

commit 3bce82377f683870cc89925ff43aefb7dcce4a77
vla: evaluate operand of sizeof if its type is a vla

	gdb/
	* eval.c (evaluate_subexp_for_sizeof): Add enum noside argument.
	(evaluate_subexp_standard): Pass noside argument.
	(evaluate_subexp_for_sizeof) <BINOP_SUBSCRIPT>: Handle subscript case
	if noside equals EVAL_NORMAL. If the subscript yields a vla type
	re-evaluate subscript operation with EVAL_NORMAL to enable sideffects.
	* gdbtypes.c (resolve_dynamic_bounds): Mark bound as evaluated.
	* gdbtypes.h (enum range_flags): Add RANGE_EVALUATED case.
