[lto] Remove dump_block_tree

[Diego Novillo <dnovillo at google dot com>]

Thanks to Honza for pointing out the existing block scope dumping
routines (dump_scope_blocks).

The whitespace changes in dump_block_node are to make it
identical to the version I committed to mainline earlier.

Tested on x86_64.


Diego.


	* tree-pretty-print.c (dump_block_node): Tidy white
	space in dump.
	* tree.c (dump_block_tree): Remove.
	(debug_block_tree): Remove.
	* tree.h (dump_block_tree): Remove.
	(debug_block_tree): Remove.
