I'd like to remove -many from the options passed by default to the
assembler, on the grounds that a gcc bug in instruction selection (eg.
emitting a power9 insn for -mcpu=power8) is better found at assembly
time than run time.
For now, just do this when --enable-checking or gcc is not a release.
This patch also emits .machine assembler directives for ELF targets
when functions are compiled for different cpus via attributes or
pragmas. That's necessary when the initial -m<cpu> option passed to
the assembler doesn't enable the superset of all opcodes emitted, as
seen by a failure of gcc.target/powerpc/clone2.c without .machine
when building gcc for power8.
rs6000_machine_from_flags deliberately uses ISA_2_4_MASKS rather than
ISA_2_2_MASKS for power5 because "friz" and other similar instructions
enabled by gcc with TARGET_FPRND are enabled in gas by "-mpower5".
(gas -mpower5 supports power5+ too.) rs6000-cpus.def puts
OPTION_MASK_FPRND in ISA_2_4_MASKS, so ISA_2_4_MASKS is the one to use
in deciding to pass "-mpower5" to gas.
O3-pr70130.c also failed on an earlier version of this patch (when
only testing one ISA bit to determine .machine). This is a test for a
power7 vector bug, but on power8 hw check_vect_support_and_set_flags
passes -mpower8-vector which means the test isn't exercising the
original bug exactly. I reckon that is wrong, and similary for other
vector testcases that ask for a specific cpu. I've fixed it here by
explicitly passing -mno-power8-vector and similar vector options.

Gimple jump threading does not duplicate forwarder blocks that might
be present before or after the second copied block. This silently
drops debug binds and markers that might be present in them. This
patch attempts to preserve them.
For blocks after either copied block, we attempt to append debug stmts
to the copied block, if it does not end with a block-ending stmt.
Failing that, for blocks between both copied blocks, we prepend its
debug stmts to the copy of the second block.
If everything fails, we still drop debug stmts on the floor, though
preexisting code consolidates debug binds in the block that threading
flows into, so only markers are really lost. We can't do much better
than that without conditional binds and markers, or debug stmts in
edges, or somesuch.
If we append debug stmts to a reusable template block, we copy it
after splitting out the debug stmts, and before putting them back.

Upstream will drop support for Python 2.x on January 1, 2020. This
patch converts the contrib/mklog script to Python 3. The process for
the conversion was as follows.
- Use the futurize tool (https://python-future.org ) to apply the
print_with_import, except, and dict transformations.
- Remove the "from __future__ import print_function".
- Change the shebang line to search for python3 in the environment.
- Modify the run() function to return a str instead of bytes.
- Update the copyright year.
