- Use representation information provided by the type system to skip SMI checks. - Fix combining of ChangeTaggedToFloat64 with JSToNumber now that JS operators can produce control. - Remove the unnecessary abstraction of smi/field offsets. - Improve unit test coverage. - Various cosmetic fixes.

A CompilationInfo constructed from just an Isolate* and a Zone* is in weird an inconsistent state (calling e.g. flags() on it will crash), so we need to avoid them. This CL removes almost all of them, the remaining 2 call sites in (for testing only) will be handled in a separate CL. Things which have been changed: * Linkage is basically a decorator for CallDescriptor now. * ChangeLowering doesn't need Linkage at all. * JSGenericLowering doesn't need a full CompilationInfo*, just a single flag. * JSContextSpecializer doesn't need the full CompilationInfo, just a Context. * Removed unused CompilationInfo from SimplifiedLoweringTester. This nicely decouples things already a bit more, but there's still work to do... Review URL: https://codereview.chromium.org/899803003 Cr-Commit-Position: refs/heads/master@{#26580}

FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use more than one of these. The Google C++ style guide even requires this, see http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Inheritance. While we're here, port r24662 to x87. The net result is that v8 compiles again with a current clang. BUG=v8:3753 LOG=y Review URL: https://codereview.chromium.org/797943002 Cr-Commit-Position: refs/heads/master@{#25792}

This does the following optimization during ChangeLowering: ChangeTaggedToFloat64(JSToNumber(x)) => if IsSmi(x) then ChangeSmiToFloat64(x) else let y = JSToNumber(x) in if IsSmi(y) then ChangeSmiToFloat64(y) else LoadHeapNumberValue(y) Also cleanup/rearrange some code duplication in ChangeLowering.

Disable some changes tests on ARM64. Also, fix the changes lowering to not use the more expensive TruncateFloat64ToInt32, but to use ChangeFloat64ToInt32/ChangeFloat64ToUint32, as it was before.
