Introduce log1p and expm1 primops

Previously log and exp were primitives yet log1p and expm1 were FFI
calls. Fix this non-uniformity.

Handle trailing path separator in package DB names (#16360)

Package DB directories with trailing separator (provided via
GHC_PACKAGE_PATH or via -package-db) resulted in incorrect calculation of
${pkgroot} substitution variable.  Keep the trailing separator while
resolving as directory or file, but remove it before dropping the last
path component with takeDirectory.

Closes #16360.

Fix #16517 by bumping the TcLevel for method sigs

There were actually two bugs fixed here:

1. candidateQTyVarsOfType needs to be careful that it does not
   try to zap metavariables from an outer scope as "naughty"
   quantification candidates. This commit adds a simple check
   to avoid doing so.

2. We weren't bumping the TcLevel in kcHsKindSig, which was used
   only for class method sigs. This mistake led to the acceptance
   of

     class C a where
       meth :: forall k. Proxy (a :: k) -> ()

   Note that k is *locally* quantified. This patch fixes the
   problem by using tcClassSigType, which correctly bumps the
   level. It's a bit inefficient because tcClassSigType does other
   work, too, but it would be tedious to repeat much of the code
   there with only a few changes. This version works well and is
   simple.

And, while updating comments, etc., I noticed that tcRnType was
missing a pushTcLevel, leading to #16767, which this patch also
fixes, by bumping the level. In the refactoring here, I also
use solveEqualities. This initially failed ghci/scripts/T15415,
but that was fixed by teaching solveEqualities to respect
-XPartialTypeSignatures.

This patch also cleans up some Notes around error generation that
came up in conversation.

Test case: typecheck/should_fail/T16517, ghci/scripts/T16767

Add disable/enable commands to ghci debugger #2215

This patch adds two new commands `:enable` and `:disable` to the GHCi debugger.
Opposite to `:set stop <n> :continue` a breakpoint disabled with `:disable` will
not loose its previously set stop command.
A new field breakEnabled is added to the BreakLocation data structure to
track the enable/disable state. When a breakpoint is disabled with a `:disable`
command, the following happens:

The corresponding BreakLocation data element is searched dictionary of the
`breaks` field of the GHCiStateMonad. If the break point is found and not
already in the disabled state, the breakpoint is removed from bytecode.
The BreakLocation data structure is kept in the breaks list and the new
breakEnabled field is set to false.

The `:enable` command works similar.

The breaks field in the GHCiStateMonad was changed from an association list
to int `IntMap`.

rts: Separate population of eventTypes from initial event generation

Previously these two orthogonal concerns were both implemented in
postHeaderEvents which made it difficult to send header events after RTS
initialization.

Hadrian: need CPP preprocessor dependencies #16660

Use the new -include-cpp-deps ghc option (#16521)
when generating .dependencies files in hadrian.
This is version gated as -include-cpp-deps is a
relatively new option.

Remove CPP ensuring word size is 32 or 64 bits around Addr# <-> int# primops

It shouldn't be needed these days, and those primops are "highly
deprecated" anyways.

This fits with my plans because it removes one bit of target-dependence
of the builtin primops, and this is the hardest part of GHC to make
multi-target.

rts: Fix RetainerProfile early return with TREC_CHUNK

When pop() returns with `*c == NULL` retainerProfile will immediately
return. All other code paths is pop() continue with the next stackElement
when this happens so it seems weird to me that TREC_CHUNK we would suddenly
abort everything even though the stack might still have elements left to
process.

base: Mark CPUTime001 as fragile

As noted in #16224, CPUTime001 has been quite problematic, reporting
non-monotonic timestamps in CI. Unfortunately I've been unable to
reproduce this locally.
