When working on LLVM/CCG, we found that the generated tree had a wrong
reference before declaration usage. Fixed for LLVM/CCG. The issue might
still be latent with Modify_Tree_For_C, but this expansion will
disappear in the future, so not worth bothering.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* exp_ch6.adb (Expand_Call): Properly split
Transform_Function_Array and Modify_Tree_For_C.
