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. Patch by Greg Price. [ruby-core:47970] [Bug #7158] git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
