[optimizing] Improve 32 bit long shift by 1. Also change FOO << 1 to FOO+FOO in the instruction simplifier. This is an architecture independent simplification, which helps 'long << 1' for 32 bit architectures. Generate an add/adc for long << 1 in x86, in case something is generated after the simplifier. Add test cases for the simplification. Change-Id: I0d512331ef13cc4ccf10c80f11c370a10ed02294 Signed-off-by: Mark Mendell <mark.p.mendell@intel.com>
