Expression is always true

[AppChecker]

Hi!

These expressions:

1. src-IL/src/il_states.cpp if (Param >= 0 || Param <= 2) {
2. src-IL/src/il_states.cpp if (Param >= -1 || Param <= 255) {
3. src-IL/src/il_states.cpp#

#define IL_DXT1             0x0706
#define IL_DXT5             0x070A
if (Param >= IL_DXT1 || Param <= IL_DXT5 ...) {

is always true (for any value of Param variable).
