Testing equality of booleans to true or false

When using booleans, it is unnecessary to test whether they’re equal to true (rule 185) or false (rule 186). Simply testing the boolean results in cleaner code.

VHDL
signal valid: boolean;
-- some code omitted
if valid then
   -- ...
end if;

if valid = true then
   -- ...
end if;

if not valid then
   -- ...
end if;

if valid = false then
   -- ...
end if;

if valid /= true then
   -- ...
end if;

Note that the equals-false rule (186) is disabled (set to IGNORE) by default.

Rule configuration

These rules can be disabled for your project, or their severity and parameters can be modified in the project linting settings. Alternatively, they can be manually configured using one of the following templates, depending on the type of project you use.

For Modular Projects, add these entries to your project's .sigasi/settings.json settings file. To scope the settings to a specific folder or file instead of the whole project, place them inside an @override block; to scope them to a specific target, place them inside a @targets block.
JSONC
```
{
    "vhdl.rules.185.severity": "{ERROR|WARNING|INFO|IGNORE}",
    "vhdl.rules.186.severity": "{ERROR|WARNING|INFO|IGNORE}"
}
```
For Classic Projects, add the VHDL lines to .settings/com.sigasi.hdt.vhdl.linting.prefs and the Verilog/SystemVerilog lines to .settings/com.sigasi.hdt.verilog.linting.prefs:
PREFS
```
185/severity/${path}={error|warning|info|ignore}
186/severity/${path}={error|warning|info|ignore}
```
