Release Engineering: Version bump to 2.15.0.
The calculatons for signed and unsigned type of lowest rank wereexpensive when there were a large number of constant expressions in theprogram. This commit improves performance by: 1. Creating classes to represent the set of integer constantexpressions and integer constants in the program. 2. Creating a candidate table of IntegralTypes for each known constantinteger value in the program, to avoid duplicate work. 3. Calculating the stlr and utlr for each constant value, not eachconstant expression.
This improves the performance of Rule 10.5 by computing all the types ofthe cast first, before determining whether they were invalid. Previouslythe join orderer found the essential type category of the "from" type,then joined that will invalid type categories, then joined that with allexpressions of that type before filtering down to the cast.
Performance Hotfix for 2.15.1

Description
Mergeback to main.
Change request type
.ql,.qll,.qlsor unit tests)Rules with added or modified queries
Release change checklist
A change note (development_handbook.md#change-notes) is required for any pull request which modifies:
If you are only adding new rule queries, a change note is not required.
Author: Is a change note required?
🚨🚨🚨
Reviewer: Confirm that format ofshared queries (not the .qll file, the
.ql file that imports it) is valid by running them within VS Code.
Reviewer: Confirm that either a change note is not required or the change note is required and has been added.
Query development review checklist
For PRs that add new queries or modify existing queries, the following checklist should be completed by both the author and reviewer:
Author
As a rule of thumb, predicates specific to the query should take no more than 1 minute, and for simple queries be under 10 seconds. If this is not the case, this should be highlighted and agreed in the code review process.
