As proposed in SE-0107: UnsafeRawPointer:
Rename 'init(allocatingCapacity:)' to 'UnsafeMutablePointer.allocate(capacity:)'
Rename 'deallocateCapacity' to 'deallocate(capacity:)'
`allocate` should not be an initializer. It's primary function is to allocate
memory, not initialize a pointer.
All four of the Unsafe*BufferPointer range subscript getter tests (one for each range) were using the same test name string. This caused only one of the four tests to actually be registered to the test suite. This change fixes that issue, and adds a couple more tests for better coverage.
Changes:
- Added bounds checks to Unsafe*BufferPointer's subscript getter and setter
- Added tests for Unsafe*BufferPointer's subscript getter for all four range types
