ee819aedf3 objtool: Make unwind hint definitions available to other architectures
Unwind hints are useful to provide objtool with information about stack
states in non-standard functions/code.

While the type of information being provided might be very arch
specific, the mechanism to provide the information can be useful for
other architectures.

Move the relevant unwint hint definitions for all architectures to
see.

Header include/linux/objtool.h contains both C and assembly definition that
are visible regardless of the file including them.

Place definition under conditional __ASSEMBLY__.

00089c048e objtool: Rename frame.h -> objtool.h
Header frame.h is getting more code annotations to help objtool analyze
object files.

Rename the file to objtool.h.
