revert r340137: [CodeGen] add rotate builtins

At least a couple of bots (gcc host compiler on PPC only?) are showing the compiler dying while trying to compile.

-* ``__builtin_rotateleft32``

-**Syntax**:

-     __builtin_rotateleft32(x, y)
-
-**Examples**:
-
-.. code-block:: c++
-

-**Description**:
-
-The '``__builtin_rotateleft``' family of builtins is used to rotate
-the bits in the first argument by the amount in the second argument. 
-For example, ``0b10000110`` rotated left by 11 becomes ``0b00110100``.
-The shift value is treated as an unsigned amount modulo the size of
-the arguments. Both arguments and the result have the bitwidth specified
-by the name of the builtin.

-The '``__builtin_rotateright``' family of builtins is used to rotate
