[RFC][PATCH 1/5] x86/ftrace: Rename mcount_64.S to ftrace.S

[Steven Rostedt]

From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>

With the advent of -mfentry that uses the new "fentry" hook over mcount, the
mcount name is obsolete. Having the code file that ftrace hooks into called
"mcount*.S" is rather misleading. Rename it to ftrace.S
