[patch] minor bitmap.c GATHER_STATISTICS fix-ups

[Steven Bosscher <stevenb dot gcc at gmail dot com>]

Hello,

This patch fixes a bunch of smaller issues with GATHER_STATISTICS for
bitmaps: overflows in counters and ugly output format.

Bootstrapped (with and without GATHER_STATISTICS) and regtested on
powerpc64-unknown-linux-gnu and on x86_64-unknown-linux-gnu. OK for
trunk?

Ciao!
Steven


	* bitmap.c (struct bitmap_descriptor_d): Use unsigned HOST_WIDEST_INT
	for all counters.
	(struct output_info): Likewise.
	(register_overhead): Remove bad gcc_assert.
	(bitmap_find_bit): If there is only a single bitmap element, do not
	count a miss as a search.
	(print_statistics): Update for counter type changes.
	(dump_bitmap_statistics): Likewise.  Print headers such that they
	are properly lined up with the printed counters.
