[Bug #19319] Fix crash in rb_str_casemap

	The following code crashes on my machine:

	```
	GC.stress = true

	str = "testing testing testing"

	puts str.capitalize
	```

	We need to ensure that the object `buffer_anchor` remains on the stack
	so it does not get GC'd.

84bf4d2ce5 Term fill in String#{,l,r}strip! even when SHARABLE_MIDDLE_SUBSTRING 
Each of these methods calls str_modify_keep_cr before
term filling, which should ensure the backing string
uses private memory, and therefore term filling should
not affect other strings.

Skipping the term filling was added in
a707ab4bc8.

2fb435b3ab Add Related link from String#hash to Object#hash 
We came across a bug in our code because we assumed `String#hash` to be consistent across Ruby processes, which was incorrect.

Our search lead us to `Object#hash` which has the right warning that `String#hash` doesn't. We also noticed that a previous version of the documentation for `String#hash` pointed to `Object#hash` that was removed by https://github.com/ruby/ruby/pull/3565.
We think this removal might not be intended and just got missed amidst other changes.
