This patch reapplies commit 759948467ea. Patch was reverted due to a clang-tidy test fail on Windows. The test has been modified. There are no additional code changes. Patch was tested with ninja check-all on Windows and Linux. Summary of code changes: Clang currently crashes for switch statements inside a template when the condition is a non-integer field member because contextual implicit conversion is skipped when parsing the condition. This conversion is however later checked in an assert when the case statement is handled. The conversion is skipped when parsing the condition because the field member is set as type-dependent based on its containing class. This patch sets the type dependency based on the field's type instead. This patch fixes Bug 40982.
