AC_PROG_CC already sets the necessary compiler flags
to enable the latest language standard.

Checking the source code is appropriate for a linter,
not for the configure script.

The boot script performs two tasks
- it checks for the presence of boot packages
- it runs autoreconf in each boot package

The first task is not valuable enough and likely could be implemented
within autoconf.

The second task be implemented in a standardised way using the macro
AC_CONFIG_SUBDIRS.

Checking LLVM version introduces complexity for not enough benefits.
Trust the users and let them deal with the consequences.

There is little value in generating a C array from a Python list.

This patch adds two commands to GHC:
- --print-prim-module: prints the contents of GHC.Internal.Prim
- --print-prim-wrappers-module: prints the contents of GHC.Internal.PrimopWrappers

These two commands can be used in ghc-internal's Setup.hs to generate
these modules. This ensures that ghc-internal's primop code is always in
sync with the GHC that builds it. It also avoids having to share code
(primops.txt.pp and friends) between ghc-internal and ghc.

(cherry picked from commit 4186a40)

Instead of the _thr _debug, ... suffix logic, we now use the flags as recorded by cabal to pick the appropriate RTS.
