ObjectPoolLinter 1.1.0

Added

• OPL001 reports a struct that is boxed as it is created in a hot path: object o = new MyStruct();,
  a cast to object or an interface, or a struct passed or returned as one. The message names the
  target type: 'new MyStruct boxed to object' allocates inside the frequently-called method 'Update'.
  Previously the value-type filter dropped these before the conversion was considered. Boxing an
  existing value (object o = count;), new int?() (which boxes to null) and struct calls to
  non-overridden object methods are still not reported. Closes A8.
• On a boxed struct, the TODO-comment fix suggests keeping the value typed as the struct or reusing a
  single box. The object-pool Get() fix is not offered there, because a pooled struct is boxed
  again at the same conversion.
• The sample boxes a Vector3 in Update; build/verify-sample.ps1 expects the new warning.

Changed

• Removed a dead clause from the value-type check in the OPL001 analyzer:
  type.IsValueType && type is not IArrayTypeSymbol is now type.IsValueType. Array types are
  never value types, so the second clause could not change the result. No behavior change.
  Closes A7.
