Jonas Toth 46ae26e7eb [clang-tidy] implement new check 'misc-const-correctness' to add 'const' to unmodified variables 
This patch connects the check for const-correctness with the new general
utility to add `const` to variables.
The code-transformation is only done, if the detected variable for const-ness
is not part of a group-declaration.

The check allows to control multiple facets of adding `const`, e.g. if pointers themself should be
marked as `const` if they are not changed.

David Chisnall 94c3b16978 Fix crash in ObjC codegen introduced with 5ab6ee7599 
5ab6ee7599 assumed that if `RValue::isScalar()` returns true then `RValue::getScalarVal` will return a valid value.  This is not the case when the return value is `void` and so void message returns would crash if they hit this path.  This is triggered only for cases where the nil-handling path needs to do something non-trivial (destroy arguments that should be consumed by the callee).

Simon Pilgrim 293899c64b [X86] Don't assume an AND/ANDNP element is undef/undemanded just because one element is undef 
For mask ops like these, the other operand's corresponding element might be zero (result = zero) - so we must demand all the bits and that element.

This appears to be what D128570 was trying to fix - both sides of the funnel shift mask of the vXi64 (legalized to v2Xi32) were incorrectly simplifying the upper 32-bit halves to undef, resulting in bad folds later on.

I intend to address the test case regressions, but this close to the release branch I'd prefer to get a fix in first.
