dd821bc564 Revert "Increase accuracy of float -> fixed in ICC code"
This reverts commit ef8dda227b.

Reason for revert: This is breaking WebKit layout tests on linux and blocking the autoroller. Probably just needs a rebase. See:
https://storage.googleapis.com/chromium-layout-test-archives/linux_trusty_blink_rel/20229/layout-test-results/results.html

ac0e705af1 Fix new IT blocks ARMv8
ARMv8 specifies that an IT block should be followed by only one 16-bit instruction.
* SkFloatToFix is back to a C implementation that mirrors the assembly code.

* S32A_D565_Opaque_neon switched the usage of the temporary 'ip' register to let
the compiler choose what is best in the context of the IT block. And replaced
'keep_dst' by 'ip' where low register or high register does not matter.

3f490cc642 Make SkFixedRound/Ceil/FloorToFixed as inline func
The macros that we were using will return unsigned int32 instead of
signed int32 because of the last 0xFFFF0000 mask. That may bring
problems if we right shift that result.

Special thanks to mtklein@google.com for helping me find out this issue.
