Spin-off issue from: https://issues.dlang.org/show_bug.cgi?id=13952

 The amount of code generated for the constructor is still worrisome.
 Especially the part that initializes X86Reg, because it initializes every
field individually, it constructs a temporary on the stack only to end up
loading zero into edx.
