re PR ipa/44563 (GCC uses a lot of RAM when compiling a large numbers of functions)

PR middle-end/44563
* tree-inline.c (gimple_expand_calls_inline): Walk BB backwards
to avoid quadratic behavior with inline expansion splitting blocks.
* tree-cfgcleanup.c (cleanup_tree_cfg_bb): Do not merge block
with the successor if the predecessor will be merged with it.
* tree-cfg.c (gimple_can_merge_blocks_p): We can't merge the
entry block with its successor.
