9c6b24cc3a [X86] updating TTI costs for arithmetic instructions on X86\SLM arch. 
updated instructions:
pmulld, pmullw, pmulhw, mulsd, mulps, mulpd, divss, divps, divsd, divpd, addpd and subpd.

special optimization case which replaces pmulld with pmullw\pmulhw\pshuf seq. 
In case if the real operands bitwidth <= 16.

06d5a1641d Do a sweep over move ctors and remove those that are identical to the default. 
All of these existed because MSVC 2013 was unable to synthesize default
move ctors. We recently dropped support for it so all that error-prone
boilerplate can go.

No functionality change intended.

c2d82ef29f [WebAssembly] Remove the override of haveFastSqrt. 
The default implementation in BasicTTI already checks TLI and does
the right thing.

b5ebaf3ae5 Unbreak WebAssembly build 
Summary: D11021 and D11045 didn't update the WebAssembly target's code. It's still experimental so all tests passed.
