Add -Wtautological-compare to -Wall Some warnings in -Wtautological-compare subgroups are DefaultIgnore. Adding this group to -Wmost, which is part of -Wall, will aid in their discoverability. Differential Revision: https://reviews.llvm.org/D69292

[Sema] Remove a -Wrange warning from -Wall During the review of D73007 Aaron Puchert mentioned `warn_for_range_variable_always_copy` shouldn't be part of -Wall since some coding styles require `for(const auto &bar : bars)`. This warning would cause false positives for these users. Based on Aaron's proposal refactored the warnings: * -Wrange-loop-construct warns about possibly unintended constructor calls. This is part of -Wall. It contains * warn_for_range_copy: loop variable A of type B creates a copy from type C * warn_for_range_const_reference_copy: loop variable A is initialized with a value of a different type resulting in a copy * -Wrange-loop-bind-reference warns about misleading use of reference types. This is not part of -Wall. It contains * warn_for_range_variable_always_copy: loop variable A is always a copy because the range of type B does not return a reference Differential Revision: https://reviews.llvm.org/D73434

Add a warning for builtin_return_address/frame_address with > 0 argument Clang is missing a warning for builtin_return_address/builtin_frame_address called with > 0 argument. Gcc provides a warning for this via -Wframe-address: https://gcc.gnu.org/onlinedocs/gcc/Return-Address.html As calling these functions with argument > 0 has caused several crashes for us, we would like to have the same warning as gcc here. This diff adds the warning and makes it part of -Wmost. Differential Revision: https://reviews.llvm.org/D75768
