Remove unused startIgnoringLeaks and stopIgnoringLeaks functions

These functions were used in earlier DumpRenderTree mac port of WebKit project.
Please refer to <https://trac.webkit.org/changeset/19364>; for details.

As DumpRenderTree has been removed in chromium project, these functions can be removed.
So this patch deletes those.

Oops, sorry Adam. My mistake.
I will update description soon. :)

[kangil_, 2013-07-15 02:02:57]

Done. :)
@abarth: Would you please take a look at this patch?
Thx in advance!! :)

Nothing ever calls startIgnoringLeaks or stopIgnoringLeaks why don't we just
remove these APIs? Are they useful in gdb?

I'm not sure this CL is worth landing.  These seem like diagnostic functions
that are part of a tool I don't understand.  To review this CL, I'd need to
study the history of these functions and understand what purpose they serve or
did serve.

[abarth-chromium, 2013-07-15 06:19:48]

To be clear, I'm not opposed to removing these functions, but we should
understand their purpose before removing them.

[kangil_, 2013-07-15 06:51:12]

IMHO, we can delete these functions since seems they were used in earlier
DumpRenderTree(which is not used in chromium anymore, actually deleted) mac
port. Please refer to https://trac.webkit.org/changeset/19364

So I would like to modify this CL as a deletion patch for those two functions.

Dear Adam and Elliot,
Thoughts?

Makes sense.  LGTM
