    When the compiler failed to evaluate a numeric constant because
    because it was erroneous, there was no way for parent nodes to
    discover the error and lower themselves into error nodes.  This patch
    now uses the NC_INVALID enumerator to mark numeric constants with a
    known, reported error.

    Fixes golang/go#11541.

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

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.
