re PR rtl-optimization/12142 (-fnon-call-exceptions generates incorrect code)

PR optimization/12142
* cse.c (count_reg_usage): In a SET with a REG SET_DEST, count the
uses of the register in the SET_SRC.  Remove unnecessary argument.
* pa.c (legitimize_pic_address): Before reload, use a scratch register
for the intermediate result in loading the address of a SYMBOL_REF.
Set the MEM_NOTRAP_P flag for the MEM.  Add a REG_EQUAL to the insn
which loads the SYMBOL_REF address.
