Yukihiro "Matz" Matsumoto 465e634d48 mruby-regexp: fix SEGV on uninitialized Regexp's hash and == ...

regexp_init() called re_compile() before setting @source / @flags
IVs, so a Regexp that survived a compile-time exception (e.g. picked
up via ObjectSpace.each_object after `Regexp.new("(")` raised) was
left with no @source. obj.hash then dereferenced nil through
mrb_str_hash() and crashed.

Set the IVs before re_compile(), and make regexp_hash / regexp_eql
defensive against a non-String @source so Regexp.allocate.hash also
behaves.
