GBE: adjust instruction order for load/function call for vector.
The previous implementation generates code as below:
%33 = extractelement <4 x i8> %32, i32 0
%34 = extractelement <4 x i8> %32, i32 1
%35 = extractelement <4 x i8> %32, i32 2
%36 = extractelement <4 x i8> %32, i32 3
%32 = load <4 x i8> addrspace(1)* %31, align 4, !tbaa !3
It may bring some potential problems in the consequent optimization pass.
Now fix adjust the extractelement instruction after the load instruction.
%32 = load <4 x i8> addrspace(1)* %31, align 4, !tbaa !3
%33 = extractelement <4 x i8> %32, i32 0
%34 = extractelement <4 x i8> %32, i32 1
%35 = extractelement <4 x i8> %32, i32 2
%36 = extractelement <4 x i8> %32, i32 3
This patch also move the dead code elimination pass after the scalarize pass.
As after scalarize pass, there may be some opportunity to remove more dead
instructions.
