When building with --with-tune=zEC12 and calling the resulting gcc
with --march=z13 (no extra -mtune), the binary would unexpectedly be compiled
with -march=z13 -mtune=zEC12. This patch avoids using the default tune
parameter if -march is specified as argument but the user can still
explicitly state -march=z13 -mtune=zEC12.
gcc/ChangeLog:
2018-06-26 Robin Dapp <rdapp@linux.vnet.ibm.com>
* config/s390/s390.h (enum processor_flags): Do not use
default tune parameter when -march was specified.

We didn't split cross-partition ranges in loclists to output a
whole-function location expression, but with nonzero locviews, we
force loclists, and then we have to split to avoid cross-partition
list entries.

This CL ports recent enhancements of the escape analysis in the
gc compiler to gofrontend.
- CL 99335: unnamed receiver should not escape.
- CL 105257: propagate loop depth to field. This prevents it
from escaping when a field's address is taken inside a loop
(but not otherwise escape).
- CL 107597: use element type for "indirection" of slice/string.
This prevents the slice/string from escaping when only the
element, in case that it is pointerless, flows to outer scope.
