Shaders compile as Shader Model 4+ even though the Graphics API is set to OpenGLES2 and Shaders are set to target Shader Model 2

Sep 26, 2019

To reproduce:
1. Open the user's attached project
2. Select the "SahderBug" shader in the Assets folder
3. Set the Compiled code only on OpenGLES20
4. Compile and show
5. Scroll to line 67, the exact line might differ from version to version

Expected: Compiling the shader does not produce any operators that are not compatible with devices that don't support Shader Model 4
Actual: Compiling a certain bit of shader code results in bitwise operator

Reproduced with: 2018.3.0a1, 2018.4.11f1, 2019.2.9f1, 2019.3.0b6,
Not reproduced with: 2017.4.33f1, 2018.2.13f1

2020.1.0a8 output differs from all the others so it's hard to say if it reproduces the issue or not
