testharnessreport: Hide elements in tests by removing them from the document tree, instead of visibility:hidden.

This fixes the flakiness of web-platform-tests/webrtc/datachannel-
emptystring.html.

[1] made the test flaky because:
 - It added a chance to invoke onSendChannelOpen()
 - It prints some lines into <div id=msg>.
 - Text dump of visibility:hidden doesn't remove EOLs represented by
   <br>s.

This CL resolves this issue by removing elements completely by
body.textContent = ''.  Setting display:none instead of visibility:hidden
also works, but body.textContent = '' is much simpler.

We're now hitting a bunch of out-of-virtual-address-spaces in various benchmarks
(e.g., tiny-innerHTML-setter.html, PseudoClassSelectors.html etc) on oilpan Linux builds.

The reason is that a GC is never scheduled during the benchmark because the current
GC heuristic is improper. In short, we're hitting a scenario like this:

- allocatedObjectSize = 3 GB
- markedObjectSizeAtLastCompleteSweep = 5 MB
- partitionAlloc = 1 GB

This doesn't hit the GC condition because (3 GB + 5 MB + 1 GB) / (5 MB + 1 GB)
is not large enough.

(Note: Accurately speaking, the esimated size becomes smaller than (5 MB + 1 GB)
as the number of collected persistent handles increases, but in those benchmarks
persistent handles are not collected so aggressively.)

This is clearly insane and we should have a way to trigger a GC
if the allocatedObjectSize is X% larger than the markedObjectSizeAtLastCompleteSweep.

With that motivation, this CL changes the GC condition as follows:

- Trigger a GC if a growing rate of PartitionAlloc _or_ Oilpan's heap is larger than X%.

Almost all validations in texImage2DBase() and texSubImage2DBase() have been done in 
their callers. These validations are executed twice. It is not necessary. For example, 
validateTexFuncParameters() is not very cheap. it is called in texImage2DBase(). This

both validateTexFunc() and texImage2DBase().

Only block containers that don't establish new formatting contexts are
allowed to ignore (and thus potentially overlap with) floats.

This obviously also applies inside multicol, but we had a check that actively
prevented that. This was some residue from CSS regions support (shared
implementation with multicol), which had a much more sophisticated positioning
implementation, which we've removed ages ago.

Before laying out, we try to estimate and set the logical top of the child, but
it may turn out after one layout pass that the estimate was wrong, due to
margin collapsing, float clearance or pagination.

So sometimes we need to reposition and relayout once or even twice inside
layoutBlockChild(). This was done with slightly poorly duplicated code.
Refactor into positionAndLayoutOnceIfNeeded() (and
markDescendantsWithFloatsForLayoutIfNeeded()). One instance of this duplicated
code used to sit in adjustBlockChildForPagination(). Moved it into
layoutBlockChild(), to make it easier to understand what's going on (and to
give adjustBlockChildForPagination() one less thing to worry about - one
parameter removed). Renamed |result| to |newLogicalTop| in
adjustBlockChildForPagination(), and |logicalTopAfterClear| to |newLogicalTop|
in layoutBlockChild().

No behavioral changes were actually intended, but when unifying
almost-duplicated code, some changes are inevitable. Added some tests for
something that now works, and used to fail. In the subsequent layout passes we
forgot to check if the new position changed how we were affected by floats.

FormDataList::Item class represents a name string in a form data, or a value in
a form data.  A value can be a string or Blob, but a name string is always a
string.  Representing a name string by Item class is overkill.  This CL adds
m_key member to Item class.

Odd items in FormDataList::m_items represented name strings, and even items in
FormDataList::m_items represented values. Now each of items in
FormDataList::m_items represents a pair of a name string and a value.  This
makes the code much simpler.
