* tc-alpha.c: Patches to track current minimum alignment to reduce
	the number of fragments created with frag_align.
	(alpha_current_align): New static variable.
	(s_alpha_text): Reset alignment to 0.
	(s_alpha_data, s_alpha_rdata, s_alpha_sdata): Likewise.
	(s_alpha_stringer, s_alpha_space): New functions.
	(s_alpha_cons, alpha_flush_pending_output): Remove functions.
	(alpha_cons_align): New function to replace both of them.
	(emit_insn): Only align if alpha_current_align is less than 2;
	reset alpha_current_align to 2.
	(s_alpha_gprel32): Likewise.
	(s_alpha_section): New function.  Basically duplicate the other
	alpha section change hooks.  Only define for ELF.
	(s_alpha_float_cons): Simplify alignment handling.
	(md_pseudo_table): Only define "rdata" and "sdata" if OBJ_ECOFF.
	If OBJ_ELF, define "section", "section.s", "sect", and "sect.s".
	Don't define the s_alpha_cons pseudo-ops.  Do define
	s_alpha_stringer and s_alpha_space pseudo-ops.
	(alpha_align): Skip if less than current default alignment.  Set
	default alignment.
	* tc-alpha.h (md_flush_pending_output): Remove.
	(md_cons_align): Add.

	* tc-alpha.c: Add oodles of function description comments.
	(md_bignum_to_chars): Remove; there are no callers.
	(md_show_usage): Mention some more variants.
