This enables more seamless interop between Torque and CSA: Since CodeStubAssembler can now inherit from the Torque base namespace, macros defined in the base namespace can be used in CodeStubAssembler macros, even without qualification. At the same time, macros in the base namespace can refer to CodeStubAssembler macros. The only new limitation is that types defined in code-stub-assembler.h cannot be referenced in the signature of macros defined in the base namespace, since this would produce a cyclic header dependency. A work-around for this woud be to put such types (like int31 in this CL) into a separate header included by both. I (mis-)used code-assembler.h for that. Another side-effec is that types and enums defined in CodeStubAssembler have to be accessed in a qualified way from Torque. Other assemblers can now inherit from their Torque equivalent, so porting macros into the corresponding Torque namespace doesn't require any change to the existing use-sites. To avoid C++ ambiguities, the Torque-generated assemblers must not define anything also defined in Code(Stub)Assembler. This includes the type aliases for TNode, PLabel, ... My workaround is to qualify everything in the generated C++. As a drive-by fix, I had to change the formatter to avoid a situation where it doesn't compute a fixed point: putting a keyword at the beginning of a line removes the '\s' in front of it, so I replaced that with '\b'.
