Make _determine_architecture() parse more variations of file(1)'s output.

file(1) in certain distributions adds an extra space between "LSB" and
"executable" when determining the type of an executable binary.

Be more tolerant with these variations by using a regular expression to
match file(1)'s output. Additionally, pass `--bare' to file(1) since we are
not interested in the file's name in the output.

Fix the rows' height computation with vertical-align: baseline and rowspan

r140907 was careful in avoiding updating the baseline descent for
spanning cells. However it still added the non-spanning cells baseline
descent to the spanning cells' row height computation.

This change avoids the previous issue by not adding the baseline
descent in this case.

fast/replaced/preferred-widths.html is flaky on Windows.

This is a speculative fix. It's certainly wrong that we're not waiting
for the images to load before measuring their dimensions.

Disable the C4724 warning for build with VS2012.
This warning seems related with improper optimization in VS2012,
which didn't happen with VS2010.

Deleted oes-texture-half-float tests from fast/canvas/webgl.

This copy of these tests is stale. They will likely be re-added under
