Subject: getStringHash on string literals (#1140)

* WIP getStringHash

* Have a use.

* Add slang-string-hash.h/.cpp

* Use StringSlicePool for holding strings for StringHash.
Add outputBuffer to string-literal-hash.slang so value can be tested.
Ignore the GlobalHashedStringLiterals instruction on emit.

* Add all the hashed string literals to ProgramLayout.

* Add reflection support for hashed string literals to reflection test.

* Fix string literal hash test.

* Small fixes to pass test suite.

* Fix issue in serialization where IRUse is not correctly initialized.

* Fix problem initializing IRUse for string hash pass.
Remove hack from slang-ir-specialize - specially handling if user is not null.

* * Use shared builder when replacing getStringHash
* Comments for functions in slang-ir-string-hash
* Do not allow zero length string literals. Could be allowed, but doing so would require StringSlicePool to have a special case (or some other mechanism)
