You can turn off optimization using the -novopt switch like below:

vcom -novopt ....

then run the simulation using vsim command.

The other way is to disable optimizatio globally using the Modelsim.ini file in your work folder. 

[vsim]
; vopt flow
; Set to turn on automatic optimization of a design.
; Default is on
VoptFlow = 1

Change this VoptFlow = 1 to VoptFlow = 0. This will disable optimization for further compiles and simulations. This modelsim.ini file should be modified only for the project , ie, in your source/working directory
