51fcc51321 MIPS: Add the lo register to the clobber list in the madd-8.c and msub-8.c testcases. 
The lo register is not listed in the clobber list in the inline asm statement
for the madd-8.c and msub-8.c testcases.  This means that when building for the
n64 ABI GCC is free to use the lo register instead of the stack when 
saving/restoring the clobbered registers.  Then then means that it decides to 
use the msub/madd instruction to perform the "x - y * z" operation rather than 
using mul; addu/subu which the test is looking for.

31da952a49 compiler: Don't record dependencies of invalid redefinitions. 
The gofrontend would crash when trying to find the initialization
    order of a variable list where one of the listed variables was an
    invalid redefinition of another in a call statement.  This patch
    fixes initialization from call statements to consider invalid
    redefinitions before recording dependency information.
    
    Fixes golang/go#11543.
