gitlab-ci: Fix perf metric pushing

Previously we would inexplicably append the key to id_rsa.

Fixes #19225.

WorkWrap: Use SysLocal Name for Thunk Splitting (#19180)

2021-01-11T04:34:59+00:00

Since !4493 we annotate top-level bindings with demands, which leads to
novel opportunities for thunk splitting absent top-level thunks.

It turns out that thunk splitting wasn't quite equipped for that,
because it re-used top-level, `External` Names for local helper Ids.
That triggered a CoreLint error (#19180), reproducible with `T19180`.

Fixed by adjusting the thunk splitting code to produce `SysLocal` names
for the local bindings.

Fixes #19180.

Fix `not32Word#` -> `notWord32#`

2021-01-10T10:37:19+00:00

This is is correcting a mistake I unfortunately missed in !4698. But
that is a recent PR so this fix is not a compatibility hazard with
released versions of GHC.

Correct more doctests

Fix calls to varargs C function fcntl

2021-01-10T02:25:19+00:00

The ccall calling convention doesn't support varargs functions, so
switch to capi instead. See
https://ghc.gitlab.haskell.org/ghc/doc/users_guide/exts/ffi.html#varargs-not-supported-by-ccall-calling-convention

testsuite: Increase delay in conc059

2021-01-10T02:24:42+00:00

As noted in #19179, conc059 can sometimes fail due to too short of a
delay in the its Haskell threads. Address this by increasing the delay
by an order of magnitude to 5 seconds.

While I'm in town I refactored the test to eliminate a great deal of
unnecessary platform dependence, eliminate use of the deprecated
usleep, and properly handle interruption by signals.

Fixes #19179.

Natural: fix left shift of 0 (fix #19170)
