[PATCH][committed][c++ frontend]: initialize ivdep value

[Tamar Christina]

Hi All,

Should control enter the switch from one of the cases other than
the IVDEP one then the variable remains uninitialized.

This fixes it by initializing it to false.

Bootstrapped Regtested on aarch64-none-linux-gnu, x86_64-pc-linux-gnu
and no issues

Committed as obvious.

Thanks,
Tamar
