Steps to reproduce:
1. Open the attached project (ComputeIncludeCompilationExample.zip)
2. Open ComputeGlobals.compute and uncomment the 4th line and save the file
3. Go back to Unity, you will see no compilation errors
4. Open ComputeShader.compute insert an extra space somewhere and save the file
5. Go back to Unity, you will see a compilation error

Expected result: Unity should throw the error after you have changed the files included in a compute shader
Actual result: Unity does not throw the error

Note:
The compile error will also list a line inside the compute shader instead of the included file making it hard to track down where an error is occurring if multiple include files are used

Reproduced with: 5.4.5p2, 5.5.4f1, 5.6.1p2, 2017.1.0b8
