Well, no, not directly. In Direct3D9 HLSL is compiled to the same kind
of code as assembly shaders by the d3d9x library. The d3d9 dll never
sees HLSL or assembly, just compiled shaders. Direct3D10 does contain
a "D3D10CompileShader" function, but that's shader model 4.0.

No, and it's not required either. GLSL is an extension just like any
other, and should be checked runtime, just like all the other
extensions.
