Add R_386_TLS_LE as a relocation having an implicit addend.

TLS on i386 in non-PIE/PIC code seems broken right now, because we don't
properly add the addend encoded in the instruction to the resulting
offset when processing R_386_TLS_LE relocations.

[analyzer] Make CloneDetector consider macro expansions.

So far macro-generated code was treated by the CloneDetector as normal code.
This caused that some macros where reported as false-positive clones because
large chunks of code coming from otherwise concise macro expansions were treated
as copy-pasted code.

This patch ensures that macros are treated in the same way as literals/function
