[PATCH INSTALLED]: eliminate const_get_call_expr_in

["Kaveh R. GHAZI" <ghazi at caip dot rutgers dot edu>]

This patch elimiates one of the two remaining "const_" functions as
previously requested.  I had been trying to eliminate both at the same
time, but kept running into a testsuite regression I couldn't figure out.
I suspect some sort of obvious cut-n-paste typo on my part, but for the
moment I don't see it.  So splitting this one out at least makes some
progress.

Tested on sparc-sun-solaris2.10, no regressions.

Installed on mainline.

	* tree-cfg.c (is_ctrl_altering_stmt, tree_block_ends_with_call_p):
	Don't use const_get_call_expr_in.
	* tree-gimple.c (const_get_call_expr_in): Delete.
	* tree-gimple.h (const_get_call_expr_in): Likewise.
