This CL adds -d=checkptr as a compile-time option for adding instrumentation to check that Go code is following unsafe.Pointer safety rules dynamically. In particular, it currently checks two things: 1. When converting unsafe.Pointer to *T, make sure the resulting pointer is aligned appropriately for T. 2. When performing pointer arithmetic, if the result points to a Go heap object, make sure we can find an unsafe.Pointer-typed operand that pointed into the same object. These checks are currently disabled for the runtime, and can also be disabled through a new //go:nocheckptr annotation. The latter is necessary for functions like strings.noescape, which intentionally violate safety rules to workaround escape analysis limitations. Fixes #22218.
