<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Flush eventlog buffers from flushEventLog
As noted in #18043, flushTrace failed flush anything beyond the writer.
This means that a significant amount of data sitting in capability-local
event buffers may never get flushed, despite the users' pleads for us to
flush.
Fix this by making flushEventLog flush all of the event buffers before
flushing the writer.
Fixes #18043.

Move linker related code into GHC.Linker. Previously it was scattered
into GHC.Unit.State, GHC.Driver.Pipeline, GHC.Runtime.Linker, etc.
Add documentation in GHC.Linker

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Constant-folding: don't pass through GHC's Int/Word (fix #11704)
Constant-folding rules for integerToWord/integerToInt were performing
the following coercions at compilation time:
integerToWord: target's Integer -> ghc's Word -> target's Word
integerToInt : target's Integer -> ghc's Int -> target's Int
1) It was wrong for cross-compilers when GHC's word size is smaller than
the target one. This patch avoids passing through GHC's word-sized
types:
integerToWord: target's Integer -> ghc's Integer -> target's Word
integerToInt : target's Integer -> ghc's Integer -> target's Int
2) Additionally we didn't wrap the target word/int literal to make it
fit into the target's range! This broke the invariant of literals
only containing values in range.
The existing code is wrong only with a 64-bit cross-compiling GHC,
targeting a 32-bit platform, and performing constant folding on a
literal that doesn't fit in a 32-bit word. If GHC was built with
DEBUG, the assertion in GHC.Types.Literal.mkLitWord would fail.
Otherwise the bad transformation would go unnoticed.
