cris: testsuite/gcc.target/cris/biap.c: Add a Y+=X*2 to the Y+=X*4.

[Hans-Peter Nilsson]

Also, tweak the scan-assembler regexps to include a tab,
lest they may spuriously match file-paths in the emitted
assembly code, should some be added at some point.  And, add
"mul", "move" and (non-addi-)"add" to insns that shouldn't
appear.

Committed.

	* gcc.target/cris/biap.c: Add a Y+=X*2 to the Y+=X*4.
