Revert the entire VLA series.

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

	passed to sizeof is dynamic evaluate the argument to compute the length.

commit 04b19544ef6a97b62b2cc4a3170b900e046ab185
vla: enable sizeof operator for indirection

	gdb/
	* eval.c (evaluate_subexp_for_sizeof) <UNOP_IND>: Create an indirect
	value and retrieve the dynamic type size.

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.

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.
