Subject: [PATCH] respect NDEBUG.

ruby/ruby.h includes ruby/assert.h, and RUBY_NDEBUG is defined
by checking NDEBUG. In other words, NDEBUG is only seen just
after ruby/ruby.h. This patch also cheks NDEBUG just after
including ruby_assert.h.

Without this patch, assertions in array.c are always enabled.
