Mehdi Amini bf8318ccc8 [IPRA] Set callee saved registers to none for local function when IPRA is enabled. ...

IPRA try to optimize caller saved register by propagating register
usage information from callee to caller so it is beneficial to have
caller saved registers compare to callee saved registers when IPRA
is enabled. Please find more detailed explanation here
https://groups.google.com/d/msg/llvm-dev/XRzGhJ9wtZg/tjAJqb0eEgAJ.

This change makes local function do not have any callee preserved
register when IPRA is enabled. A simple test case is also added to
verify this change.
