I can not reproduce it (since I do not have the source code to Array.hs).

The symbol is:

% echo '_Z8do_printIP15LLVMOpaqueValueN4llvm5ValueEEPcT_' |c++filt
char* do_print<LLVMOpaqueValue*, llvm::Value>(LLVMOpaqueValue*)
% 

Which is in:

llvm/cbits/extra.cpp

Which means is should be possible to fix that particular missing symbol.

I try something different (since I don't have your test case) and I get
other missing symbols:

So I rebuild sys-devel/llvm with the alltargets use flag on gentoo.

I commented the PIC16 stuff in the cabal file.

I get stuck (trying to help) on this on, it is just a destructor
for a simple class that does not even declare a destructor:

% echo '_ZN4llvm12SMDiagnosticD1Ev'| c++filt     
llvm::SMDiagnostic::~SMDiagnostic()
%
