```
Example:
shader: `test.vert`
```
layout(constant_id = 100) const int myint = 10;
layout(constant_id = 101) const int myuint = 100;
layout(constant_id = 200) const float myfloat = 1.25;
layout(constant_id = 201) const double mydouble = 2.34;
void main() {}
```
command line:
```
spirv-opt --set-spec-const-default-value "100:12 101:200 200:1.2323
201:1.2345" test.vert -o output.spv
```
output:
