    The new -fgo-c-header=FILE option will write a C header file defining
    all the struct types and numeric const values in package scope.  This
    will be used when building the Go runtime package (libgo/go/runtime) to
    generate a C header file that may be included by the C code in the C
    runtime package (libgo/runtime).
    
    This will ensure that the Go code and C code are working with the same
    data structures as we convert the runtime from C to Go to upgrade to the
    current GC runtime, notably the concurrent garbage collector.

Nothing uses MQ anymore, but it still shows up in all the dump files.
This patch removes it from CALL_REALLY_USED_REGISTERS so that that does
not happen anymore (it is still a fixed register, there should be no
functional change).

Currently the fix-it validator rejects ad-hoc locations.

add_fixit_insert/replace.  Doing so requires moving get_pure_location
from gcc to libcpp.
