Chuanqi Xu 2556f58148 [FuncSpec] Don't specialize function which are easy to inline
It would waste time to specialize a function which would inline finally.
This patch did two things:

- Don't specialize functions which are always-inline.
- Don't spescialize functions whose lines of code are less than threshold
(100 by default).

For spec2017int, this patch could reduce the number of specialized
functions by 33%. Then the compile time didn't increase for every
benchmark.

Chuanqi Xu 801c2b9bba [FuncSpec] Add an option to specializing literal constant
Now the option is off by default. Since we are not sure if this option
would make the compile time increase aggressively. Although we tested it
on SPEC2017, we may need to test more to make it on by default.
