Exported from WP and cleaned up a bit.

Closes #3416
Closes #3477

There is no need for fs.readFile() to be using pread rather than read.
The default semantics of read() are such that subsequent reads are where
we want them anyway.

On Windows, full pathnames are stored in the Error object when
a file i/o error happens. This is not the case on Unix. Before
this fix the test would break because of these full paths.

In this test sending SIGKILL has the same effect as sending SIGHUP,
but SIGKILL has the advantage that it works on Windows too.

- Added a note to the cluster module documentation.
- Disabled test-cluster-http-pipe.

Fixing bugs in promotion of elements transitions (r1175). - Fixed invalid memory access when reading enum-cache from descriptor array with elements transitions but 0 real descriptors. - Fixed infinite recursion in the intrusive map iterator when visiting elements transitions. - Properly cached non-fastmode elements transitions.

Revert part of 11727 as it sometimes tanked V8 benchmark (raytrace) performance for reasons that are not obvious. Now we make objects into fast-case objects when they are made prototypes for other objects, but we do not mark objects that are already fast case with a bit that helps keep them in fast case.
