Some codegen tests were written with the assumption that arguments and results are in memory, and with a specific stack layout. With the register ABI, the assumption is no longer true. Adjust the tests to work with both cases. - For tests expecting in memory arguments/results, change to use global variables or memory-assigned argument/results. - Allow more registers. E.g. some tests expecting register names contain only letters (e.g. AX), but it can also contain numbers (e.g. R10). - Some instruction selection changes when operate on register vs. memory, e.g. ADDQ vs. LEAQ, MOVB vs. MOVL. Accept both. TODO: mathbits.go and memops.go still need fix.
