Merge pull request #3441 from kinke/fix_captured_nonpassed 
Fix ICE for *captured* parameters *not* passed on the LLVM level

Add --fno-plt option to avoid PLT external calls (#3443) 
This patch gives new option which avoids the PLT and lazy binding while
making external calls.
Implementation inspired by `-fno-plt` support to Clang.

Clang's patch: https://reviews.llvm.org/D39079

0c0102a9e4 Fix ICE for *captured* parameters *not* passed on the LLVM level 
Their IrParameter isn't created as part of DtoDeclareFunction(). Before
being able to handle that later in defineParameters() (as part of
defining the function), DtoCreateNestedContextType() steps in and
creates an IrLocal if not already created.

1) Create an IrParameter in that case in DtoCreateNestedContextType().
2) Handle these new value-less (no LL param) IrParameters in
   defineParameters().
3) Fix the iOS AArch64 ABI, as apparently not all empty structs are
   ignored for parameter passing, but only POD ones.
   Also don't ignore anything passed by reference.

967947eb84 Emulate @weak functions on Windows and don't emit COMDATs for ELF anymore 
Emulation for @weak global variables is still left out but should be
analogous.

The test adaptations are mostly a revert of 3893840f. The testcase has
shown that @weak hasn't worked properly for ELF (linker apparently
prefers the version in the 1st object file, independent of whether it's
weak or not), because the functions are emitted in COMDATs.
clang emits COMDATs for templates and inline functions only, not for
regular functions.

f4f80d32d7 Make IR type determination for captured lazy params TargetABI-agnostic 
This fixes codegen/nested_lazy_gh2302.d for AArch64, which failed due to
the TargetABI rewriting the delegate (IR struct) to `[2 x i64]`.

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.

77775a40de Use function attribute "frame-pointer" instead of "no-frame-pointer-elim"/"no-frame-pointer-elim-non-leaf" 
LLVM 8 (D56351) introduced "frame-pointer" which was intended to replace
"no-frame-pointer-elim"/"no-frame-pointer-elim-non-leaf".

d4fa4710e0 Don't emit DMD-style tracing with pragma(LDC_profile_instr, false) 
E.g., this disables it for __entrypoint.d (the C main function(s) in
there), which is required.

A wmain on Windows is not detected as FuncDeclaration.isCMain() yet,
that should be fixed too.

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).
