JF Bastien 9994b911f4 Targets: commonize some stack realignment code ... This patch does the following: * Fix FIXME on `needsStackRealignment`: it is now shared between multiple targets, implemented in `TargetRegisterInfo`, and isn't `virtual` anymore. This will break out-of-tree targets, silently if they used `virtual` and with a build error if they used `override`. * Factor out `canRealignStack` as a `virtual` function on `TargetRegisterInfo`, by default only looks for the `no-realign-stack` function attribute. Multiple targets duplicated the same `needsStackRealignment` code: - Aarch64. - ARM. - Mips almost: had extra `DEBUG` diagnostic, which the default implementation now has. - PowerPC. - WebAssembly. - x86 almost: has an extra `-force-align-stack` option, which the default implementation now has. The default implementation of `needsStackRealignment` used to just return `false`. My current patch changes the behavior by simply using the above shared behavior. This affects: - AMDGPU - BPF - CppBackend - MSP430 - NVPTX - Sparc - SystemZ - XCore - Out-of-tree targets This is a breaking change! `make check` passes. The only implementation of the `virtual` function (besides the slight different in x86) was Hexagon (which did `MF.getFrameInfo()->getMaxAlignment() > 8`), and potentially some out-of-tree targets. Hexagon now uses the default implementation. `needsStackRealignment` was being overwritten in `<Target>GenRegisterInfo.inc`, to return `false` as the default also did. That was odd and is now gone.
