Subject: [PATCH] perf(ngBind): set textContent rather than using
 element.text()

"Speeds up chrome with ~10% firefox by ~5%"

We don't really see this result in benchmarks (https://www.dropbox.com/s/76wxqbvduade52s/big_table_benchmark_b1ee5396_vs_d580a954.zip?dl=0)
However, it's basically harmless.

Side effects:

Use strict equality check for `undefined` to replace with empty string. Most target browsers will output `undefined` rather than the empty
string if we don't do this. Previously, ngBindTemplate did not perform this check. However the change has been made to make behaviour
consistent across all target browsers (chrome does output the empty string).

Closes #9369
