Add a new attribute, 'noduplicate'. If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call.

Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).

This has undefined behavior, because the classof implementation attempts to
access parts of the not-yet-constructed derived class. Found by clang

these patches are tested a lot by test-suite but
make check tests are forthcoming once the next
few patches that complete this are committed.
with the next few patches the pass rate for mips16 is

GNU disassembler recognizes an "or" instruction as a "move", and this change
makes the disassembled code easier to read.

MC disassembler clients (LLDB) are interested in querying if an
instruction may affect control flow other than by virtue of being
an explicit branch instruction. For example, instructions which
write directly to the PC on some architectures.

Refactor isIntrinsic() to be quicker, and change classof() (and thus, isa<IntrinsicInst>()) to use it. This decreases the number of occurrences of the slow-path string matching performed by getIntrinsicID().
