Code Environment setups

build environment requirements are in https://github.com/JetBrains/kotlin Readme - Java 6 and Java 7 needed
run ./gradlew publish

https://android.googlesource.com/platform/frameworks/support/+/androidx-main/README.md
https://android.googlesource.com/platform/frameworks/support/+/androidx-main/docs/onboarding.md
once set up for AndroidX, cd to frameworks/support and run ANDROIDX_PROJECTS=COMPOSE ./gradlew studio

Triggers frontend to resolve all the files https://github.com/JetBrains/kotlin/blob/master/compiler/cli/src/org/jetbrains/kotlin/cli/jvm/compiler/FirKotlinToJvmBytecodeCompiler.kt#L313
Converts Frontend IR into Backend IR - https://github.com/JetBrains/kotlin/blob/master/compiler/cli/src/org/jetbrains/kotlin/cli/jvm/compiler/FirKotlinToJvmBytecodeCompiler.kt#L189
Triggers the backend - https://github.com/JetBrains/kotlin/blob/master/compiler/cli/src/org/jetbrains/kotlin/cli/jvm/compiler/FirKotlinToJvmBytecodeCompiler.kt#L166

Useful tests:
- FirDiagnosticTestGenerated in :compiler:fir:analysis-tests: tests takes some program as input, give it to the frontend and render diagnostics reported by the frontend
- FirBlackBoxCodegenTestGenerated in :compiler:fir:fir2ir: tests takes some program as input, runs FIR, fir2ir and JVM IR backend and then runs box method from compiled code. If box returns "OK" then the test is passed
Add myShinyTest.kt to corresponding testData directory and run ./gradlew generateTests, or hit Generate All Tests run configuration in in IDEA and it will add testMyShinyto corresponding test runner
