*	[WebAssembly] Fix a regression selecting negative build_vector lanes	Thomas Lively	2019-01-31	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Summary: The custom lowering introduced in rL352592 creates build_vector nodes with negative i32 operands, but these operands did not meet the value range constraints necessary to match build_vector nodes. This CL fixes the issue by removing the unnecessary constraints.

*	[WebAssembly] Optimize BUILD_VECTOR lowering for size	Thomas Lively	2019-01-30	1	-0/+127
	Summary: Implements custom lowering logic that finds the optimal value for the initial splat of the vector and either uses it or uses v128.const if it is available and if it would produce smaller code. This logic replaces large TableGen ISEL patterns that would lower all non-splat BUILD_VECTORs into a splat followed by a fixed number of replace_lane instructions. This CL fixes PR39685.
