Hi,

debug counters can often be useful when looking into IPA-SRA related
issues and so the patch below adds one to the gate of the pass.
Bootstrapped and tested on x86_64-linux.  OK for trunk?

Thanks,

Martin

	* dbgcnt.def (eipa_sra): New counter.
	* tree-sra.c (ipa_early_sra_gate): Also check eipa_sra debug counter.
