Code coverage showed that the execSync() variable inheritStderr
was never set to the default value of true. This is because
the default case is hit whenever normalizeExecArgs() returns an
object without an 'options' property. However, this can never
be the case because normalizeExecArgs() unconditionally creates
the options object. This commit removes the unreachable code.

This is a partial revert of
14d1a8a631, which coerced the offset
of Buffer#slice() using the | operator. This causes some edge
cases to be handled incorrectly. This commit restores the old
behavior, but converts offsets to integers using Math.trunc().
This commit does not revert any tests, and adds an additional
regression test.

As shown in https://github.com/nodejs/node/issues/9096, the offset and
end value of the `slice` call are coerced to numbers and then passed to
`FastBuffer`, which internally truncates the mantissa part if the number
is actually a floating point number. This actually affects the new
length of the slice calculation. For example,
> const original = Buffer.from('abcd');
undefined
> original.slice(original.length / 3).toString()
'bc'
This happens because, starting value of the slice is 4 / 3, which is
1.33 (approximately). Now, the length of the slice is calculated as
the difference between the actual length of the buffer and the starting
offset. So, it becomes 2.67 (4 - 1.33). Now, a new `FastBuffer` is
constructed, with the following values as parameters,
1. actual buffer object,
2. starting value, which is 1.33 and
3. the length 2.67.
The underlying C++ code truncates the numbers and they become 1 and 2.
That is why the result is just `bc`.
This patch makes sure that all the offsets are coerced to integers
before any calculations are done.

Commit 93a44d5 ("src: fix deferred events not working with -e") defers
evaluation of the script to the next tick.
A side effect of that change is that 'beforeExit' listeners run before
the actual script. 'beforeExit' is emitted when the event loop is
empty but process.nextTick() does not ref the event loop.
Fix that by using setImmediate(). Because it is implemented in terms
of a uv_check_t handle, it interacts with the event loop properly.

The `path.resolve()` function when given just a drive letter such as
"C:" tries to get a drive-specific CWD, but that isn't available in
cases when the process is not launched via cmd.exe and the process
CWD has not been explicitly set on that drive.
This change adds a fallback to the process CWD, if the process CWD
happens to be on the resolved drive letter. If the process CWD is on
another drive, then a drive-specific CWD cannot be resolved and
defaults to the drive's root as before.
Based on experimentation, the fixed behavior matches that of other
similar path resolution implementations on Windows I checked: .NET's
`System.IO.Path.GetFullPath()` and Python's `os.path.abspath()`.
In the automated path test cases the issue doesn't occur when the
tests are run normally from cmd.exe. But it did cause an assertion
when running the tests from PowerShell, that is fixed by this change.
