Cache the expanded load path
* load.c (rb_get_expanded_load_path): cache the expanded load
path. This saves 4KB of allocation and some stats for every
element of the load path (so nearly a MB in my Rails app)
on every require.
* load.c (rb_construct_expanded_load_path): ensure that $LOAD_PATH
entries are frozen strings. The user must mutate $LOAD_PATH
itself rather than its individual entries.
* vm_core.h (rb_vm_struct): add fields.
* vm.c (rb_vm_mark): mark new fields.
* ruby.c (process_options): modify $LOAD_PATH directly rather than
its elements.
