[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.
