* bpo-23404: make touch becomes make regen-all (#1405)
Don't rebuild generated files based on file modification time
anymore, the action is now explicit. Replace "make touch"
with "make regen-all".
Changes:
* Remove "make touch", Tools/hg/hgtouch.py and .hgtouch
* Add a new "make regen-all" command to rebuild all generated files
* Add subcommands to only generate specific files:
- regen-ast: Include/Python-ast.h and Python/Python-ast.c
- regen-grammar: Include/graminit.h and Python/graminit.c
- regen-importlib: Python/importlib_external.h and Python/importlib.h
- regen-opcode: Include/opcode.h
- regen-opcode-targets: Python/opcode_targets.h
- regen-typeslots: Objects/typeslots.inc
* Rename PYTHON_FOR_GEN to PYTHON_FOR_REGEN
* pgen is now only built by by "make regen-grammar"
* Add $(srcdir)/ prefix to paths to source files to handle correctly
compilation outside the source directory
Note: $(PYTHON_FOR_REGEN) is no more used nor needed by "make"
default target building Python.
(cherry picked from commit a5c62a8e9f)
* bpo-30273: Update sysconfig (#1464)
The AST_H_DIR variable was removed from Makefile.pre.in by the commit
a5c62a8e9f (bpo-23404).
AST_H_DIR was hardcoded to "Include", so replace the removed variable
by its content.
Remove also ASDLGEN variable from sysconfig example since this
variable was also removed.

* bpo-30232: Support Git worktree in configure.ac (#1391)
Don't test if .git/HEAD file exists, but only if the .git file (or
directory) exists.
(cherry picked from commit 5facdbb291)
* bpo-30232: Regenerate configure (#1396)
Run autoconf.
(cherry picked from commit 9ed34a8953)
Python/dtoa.c is not compiled correctly with clang 4.0 and
optimization level -O2 or higher, because of an aliasing issue on the
double/ULong[2] union. Only compile dtoa.c with -fno-strict-aliasing.
LLVM bug report:
https://bugs.llvm.org//show_bug.cgi?id=31928
The presence of the ``--enable-optimizations`` flag is indicated by the
value of ``$enableval``, but the configure script was checking ``$withval``,
resulting in the ``--enable-optimizations`` flag being effectively ignored.

Use --short form of git hash. Use output from "git describe" for tag.
Expected outputs:
1. previous hg
2. previous git
3. updated git

* bpo-27593: Get SCM build info from git instead of hg. (#446)
sys.version and the platform module python_build(),
python_branch(), and python_revision() functions now use
git information rather than hg when building from a repo.
Based on original patches by Brett Cannon and Steve Dower.
(cherry picked from commit 5c4b0d063a)
Tested on macOS 10.11 dtrace, Ubuntu 16.04 SystemTap, and libbcc.
Largely based by an initial patch by Jesús Cea Avión, with some
influence from Dave Malcolm's SystemTap patch and Nikhil Benesch's
unification patch.
Things deliberately left out for simplicity:
- ustack helpers, I have no way of testing them at this point since
they are Solaris-specific
- PyFrameObject * in function__entry/function__return, this is
SystemTap-specific
- SPARC support
- dynamic tracing
- sys module dtrace facility introspection
All of those might be added later.
Too many build tool chains do not properly support it, including building
and linking an executable fine that simply segfaults when you try to run
it (such as debian jessie 8.5's gcc 4.9). On others where it does appear
to build (ubuntu 16.04's gcc 5.4) there are still test_distutils and test_gdb
failures to deal with.
We're not going to spend time attempting to maintain a complicated white list
of what does and doesn't work in our configure.ac file.

required for PGO linking - to be a configure time error rather than
make time when --with-optimizations is enabled. Also improve our
ability to find the llvm-profdata tool on MacOS and some Linuxes.
