Reduced precompiled source file

Gcc 4.9.0 trunk from 2013-12-28 ICEs while compiling Gentoo LLVM-3.3-r2:

x86_64-pc-linux-gnu-g++ -m32 -fvisibility-inlines-hidden -fno-exceptions -fPIC
-O2 -ggdb -pipe -march=native -mtune=native  -flto=4 -pedantic -c
./testcase.i./testcase.i: In member function ‘llvm::Value*
{anonymous}::LibCallOptimization::OptimizeCall(llvm::CallInst*,
llvm::DataLayout*, llvm::TargetLibraryInfo*, llvm::IRBuilder<>&)’:
./testcase.i:225:12: error: LHS in noreturn call
     Value *OptimizeCall (CallInst * CI, DataLayout *, TargetLibraryInfo *,
            ^
D.2995 = __builtin_unreachable (this, D.2998, 0B, MEM[(const struct IRBuilder
&)B]);
./testcase.i:225:12: internal compiler error: verify_gimple failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.gentoo.org/> for instructions

Crashes the same way without -flto.

Gcc-4.8.2 not ICEs but fails other way with -flto but succeeds without -flto.

C-reduce reduced testcase attached.
