[TableGen] Emit a warning for unused template args

Add a warning to TableGen for unused template arguments in classes and
multiclasses, for example:

  multiclass Foo<int x> {
    def bar;
  }

  $ llvm-tblgen foo.td

  foo.td:1:20: warning: unused template argument: Foo::x
  multiclass Foo<int x> {
                     ^
A flag '--no-warn-on-unused-template-args' is added to disable the
warning. The warning is disabled for LLVM and sub-projects if
'LLVM_ENABLE_WARNINGS=OFF'.

[TblGen] Extend !if semantics through new feature !cond

This patch extends TableGen language with !cond operator.
Instead of embedding !if inside !if which can get cumbersome,
one can now use !cond.
Below is an example to convert an integer 'x' into a string:

    !cond(!lt(x,0) : "Negative",
          !eq(x,0) : "Zero",
          !eq(x,1) : "One,
          1        : "MoreThanOne")
