Subject: [PATCH 3.16 339/346] ARC: use ASL assembler mnemonic

3.16.39-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Vineet Gupta <vgupta@...opsys.com>

commit a6416f57ce57fb390b6ee30b12c01c29032a26af upstream.

ARCompact and ARCv2 only have ASL, while binutils used to support LSL as
a alias mnemonic.

Newer binutils (upstream) don't want to do that so replace it.
