Adenilson Cavalcanti 4a719a7f4c Optimize harfbuzz big integer conversions
Profiling showed that type conversions were adding considerable cycles in time
spent doing text shaping.

The idea is to optimize it using native processor instructions to help Blink
layout performance.

Doing further investigation revelead that compilers may not use the
proper instruction on ARM 32bits builds (i.e. REV16).

One way to insure that the generated ASM was ideal for both gcc/clang
was using __builtin_bswap16.

Added bonus is that we no longer need to test for CPU architecture.

Ouch.  Wonder how none of the bots caught the float->int truncation.

Behdad Esfahbod 0328a1ce41 Revert b4c6113032
Was causing more trouble than it solved.  We use unsigned for indexing,
and it's not helpful to allow that wrapping to negative integers on
32bit machines.  The only way we could work around it would have been
by accepting int64_t arg, but that's overkill.

Ignore the MSVC 2008 build issue.  We don't support that compiler.

Behdad Esfahbod 52f61cdb87 Detect over/under-flow in UnsizedArray::operator[]
Was causing bad substitutions in mort table because of WordOffsetToIndex()
producing negative numbers that were cast to unsigned int and returned as
large numbers (which was desirable, so they would be rejected), but then
they were cast to int when passed to this operator and acting as small
negative integers, which was bad...

Detect overflow.  Ouch, however, now I see this still fails on 32-bit.
Guess I'm going to revert an earlier change.

That's what Apple does, and it wouldn't degrade our OpenType performance.
