* Include funTyCon in exposedPrimTyCons.
Every single place using exposedPrimTyCons was adding funTyCon
manually.
* Remove unused synTyConResKind and ieLWrappedName
* Add recordSelectorTyCon_maybe
* In exprType, panic instead of giving a trace message and dummy output.
This prevents #18767 reoccurring.
* Fix compilation error in fragile concprog001 test (part of #18732)

UNDERFLOW_FRAMEs don't have profiling headers so we have to use the
AP_STACK's function's CCS as the new frame's CCS.
Fixes one of the many bugs caught by concprog001 (#15508).

The script I used is included as testsuite/driver/kill_extra_files.py,
though at this point it is for mostly historical interest.
Some of the tests in libraries/hpc relied on extra_files.py, so this
commit includes an update to that submodule.
One test in libraries/process also relies on extra_files.py, but we
cannot update that submodule so easily, so for now we special-case it
in the test driver.

The `clean_cmd` and `extra_clean` setup functions don't do anything.
Remove them from .T files.
Created using https://github.com/thomie/refactor-ghc-testsuite. This
diff is a test for the .T-file parser/processor/pretty-printer in that
repository.
find . -name '*.T' -exec ~/refactor-ghc-testsuite/Main "{}" \;
Tests containing inline comments or multiline strings are not modified.

Summary:
The aim here is to reduce the number of remote memory accesses on
systems with a NUMA memory architecture, typically multi-socket servers.
Linux provides a NUMA API for doing two things:
* Allocating memory local to a particular node
* Binding a thread to a particular node
When given the +RTS --numa flag, the runtime will
* Determine the number of NUMA nodes (N) by querying the OS
* Assign capabilities to nodes, so cap C is on node C%N
* Bind worker threads on a capability to the correct node
* Keep a separate free lists in the block layer for each node
* Allocate the nursery for a capability from node-local memory
* Allocate blocks in the GC from node-local memory
For example, using nofib/parallel/queens on a 24-core 2-socket machine:
```
$ ./Main 15 +RTS -N24 -s -A64m
Total time 173.960s ( 7.467s elapsed)
$ ./Main 15 +RTS -N24 -s -A64m --numa
Total time 150.836s ( 6.423s elapsed)
```
The biggest win here is expected to be allocating from node-local
memory, so that means programs using a large -A value (as here).
According to perf, on this program the number of remote memory accesses
were reduced by more than 50% by using `--numa`.
Test Plan:
* validate
* There's a new flag --debug-numa=<n> that pretends to do NUMA without
actually making the OS calls, which is useful for testing the code
on non-NUMA systems.
* TODO: I need to add some unit tests

The SMP primitives were missing appropriate memory barriers
(sync, isync instructions) on all PowerPCs.
Use the built-ins _sync_* provided by gcc and clang. This
reduces code size significantly.
Remove broken mark for concprog001 on powerpc64. The referenced
ticket number (11259) was wrong.
Test Plan: validate on powerpc and ARM

The following tests fail on powerpc64 and have a ticket.
Mark those tests as expect_broken.
Here are the details:
The PowerPC native code generator does not support DWARF debug
information. This is tracked in ticket #11261. Mark the respective
tests broken on powerpc64.
testsuite: mark print022 broken on powerpc64
Ticket #11262 tracks difference in stdout for print022.
testsuite: mark recomp015 broken on powerpc64
testsuite: mark recomp011 broken on powerpc64
This is tracked as ticket #11323 and #11260.
testsuite: mark linker tests broken on powerpc64
Ticket #11259 tracks tests failing because there is no RTS
linker on powerpc64.
