We don't freeze non String object and expand it every times. We add
arguments for expanding load path partially and checking if load path
have relative paths or non String objects.
* load.c (load_path_getcwd): get current working directory for checking
if it's changed when getting load path.
* load.c (rb_get_expanded_load_path): fix for rebuilding cache properly.
We check if current working directory is changed and rebuild expanded
load path cache. We expand paths which start with ~ (User HOME) and
non String objects every times for compatibility. We make this
accessible from other source files.
* load.c (rb_feature_provided): call rb_get_path() since we changed
rb_file_expand_path_fast() not to call it.
* load.c (Init_load): initialize vm->load_path_check_cache.

compatibility related to cached 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.

test_signal_requiring of test/ruby/test_signal.rb fail if the sub
process is killed on waiting IO in lex_io_gets in rb_load_file in
rb_load_internal in require.
This is because
(1) the process receive the killing signal in
rb_thread_io_blocking_region in rb_read_internal in lex_io_gets.
(2) set th->errinfo as INT2FIX(TAG_FATAL) at
rb_threadptr_execute_interrupts_common.
(3) escape rb_load_file in rb_load_internal and jump to EXEC_TAG()
without set loaded as TRUE.
(4) call first rb_exc_raise(GET_THREAD()->errinfo); because loaded
is FALSE as above. this errinfo should be an exception object
but this is INT2FIX(TAG_FATAL).
Don't call first rb_exc_raise if GET_THREAD()->errinfo is Fixnum.
