[PATCH][committed]middle-end vect: remove unused variable in complex numbers detection code.

[Tamar Christina via Gcc-patches]

Hi All,

This removed an unused variable that clang seems to catch when
compiling GCC with Clang.

Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.

Committed under the obvious rule.

Thanks,
Tamar

gcc/ChangeLog:

        * tree-vect-slp-patterns.c (complex_mul_pattern::matches): Remove 
l1node.
