A couple of nits involving the letter 'C'.

We will periodically bump this as necessary.

This release does not build.

Silly rabbit, BlockInfoTables are data. This fixes the unregisterised build,
finally fixing #14454.

blockLbl was originally changed in 8b007abb to
use mkTempAsmLabel to fix an inconsistency resulting in #14221. However, this
breaks the C code generator, which doesn't support AsmTempLabels (#14454).

Instead let's try going the other direction: use a new CLabel variety,
LocalBlockLabel. Then we can teach the C code generator to deal with
these as well.

Previously the included package lists took a disproportionate amount of
space in the resulting document and were difficult to maintain. Turn it
into a table.

The Cabal library now commits `Lexer.hs` directly to the source tree,
so the build step where we'd call alex ourselves to generate that file
is no longer necessary, nor will it work.

Trac #14449 showed that we were failing to check that the
quantified type variables of a partial type signature remained
distinct.

See Note [Quantified variables in partial type signatures]
in TcBinds.

A little refactoring along the way.

This partially addresses #14483 by fixing the Windows implementation of
System.Environment.getExecutablePath. This is achieved by using
GetFinalPathNameByHandleW to resolve potential symlinks, while making
sure we do not get back a UNC path (see #14460).

Supposedly the original issue has been fixed.

Niklas Hambüchen authored 7 years ago and Ben Gamari committed 7 years ago

On 64-bit UNIX and Windows, Haskell `Int` has 64 bits
but C `int msecs` has 32 bits, resulting in an overflow.

This commit fixes it by switching fdReady() to take int64_t,
into which a Haskell `Int` will always fit.

(Note we could not switch to `long long` because that is
32 bit on 64-bit Windows machines.)

Further, to be able to actually wait longer than ~49 days,
we put loops around the waiting syscalls (they all accept only
32-bit integers).

Note the timer signal would typically interrupt the syscalls
before the ~49 days are over, but you can run Haskell programs
without the timer signal, an we want it to be correct in all
cases.

tar needs lbzip2 to extract the GMP tarball. Patch is needed to, well, patch.

This was unfortunately overwritten by the Hadrian README in a previous
Hadrian merge.

This broke the 32-bit build.

This output is supposed to be machine-readable; having random line-breaks
defeats this.

This refactors the dump file setup path, separating concerns a bit. It also
fixes an exception-unsafe usage of openFile.

Subtraction `y - 1` is redundant. The value of y is guaranteed to be
positive and odd, so
```
(y - 1) `quot` 2` = `y `quot` 2
```
