1d969cfcca Revise IRScope refactoring 
LLVM already provides suited RAII helper types to restore the IRBuilder
state. [They sadly aren't movable, so I've had to wrap them in a
unique_ptr.]

While at it, also minimally revise debuginfo generation for functions.

69269f3bd9 Refactor IRScope handling 
Replace the stack of IRScopes, each with its own IRBuilder, by directly
tampering with the state of a single IRBuilder.

This seems like the most feasible way to account for a breaking change
in LLVM 11, disallowing IRBuilder from being copied.

Add missing UnrolledLoopStatement to PGO region count instrumentation and calculation. Also add extra precautions to catch this problem earlier in the future. (#3524)

Fix PGO instrumentation crash for final switch(enum) statements together with -release. (#3512) 
This change includes checking of whether there is a default statement when using `case <variable>:` (LLVM IR switch instruction cannot be used), although that is currently not allowed in the D language. Therefore there is no testcase that covers that.

See GH issue #3375

684acd6a3f Improve check for multiple entry point definitions 
* Extend the error message, closely following DMD. Tested by
  fail_compilation/fail5634.d.
* Check across all compiled modules, not on a per-object-file basis.
  That's what DMD does too.
* Apply the implicit `return 0` / void -> int return type promotion to
  all D/C main functions, not just the first one. This prevents some
  potential follow-up crashes.

Refactoring: Replace Expression::op check followed by static cast to Expression::is<ExpressionType> (#3141) 
This may negatively impact performance, as the (final, i.e.,
non-virtual) Expression::is... family is implemented in D and not
available inline in the C++ headers.

d8f60d2f5c Redirect access to object.d type declarations through gen/runtime 
Not all type declarations yet (e.g., some TypeInfo subtypes are still
accessed directly), but those already wrapped as LazyType in the
gen/runtime.cpp module (with check and proper error msg in case object.d
doesn't contain a required declaration).

fffe86cd2e Introduce try-catch scopes abstraction 
Single intended functional change/fix: check ALL active catch blocks in
`isCatchingNonExceptions()`, not just the ones from the innermost
try-catch scope.

The catch bodies of a try-catch scope are now emitted in lexical order
(used to be reversed, last catch block first).
