066fcf8628 Inliner tweak. Function calls should cost more than one instruction!

ac77bfdbd4 If a function calls setjmp, never inline it into other functions. This is
a hack around the fact that we don't represent the CFG correctly for sj/lj.
It fixes PR2486.

79328661fa Adjust inline cost computation to be less aggressive.

7c3becd9d7 1. Drop default inline threshold back down to 200.
2. Do not use # of basic blocks as part of the cost computation since it doesn't really figure into function size.
3. More aggressively inline function with vector code.

8d84d5b62c Increasing the inline limit from (overly conservative) 200 to 300. Given each BB costs 20 and each instruction costs 5, 200 means a 4 BB function + 24 instructions (actually less because caller's size also contributes to it).
Furthermore, double the limit when more than 10% of the callee instructions are vector instructions. Multimedia kernels tend to love inlining.

6899b31422 Add BasicInliner interface.
This interface allows clients to inline bunch of functions with module
level call graph information.:wq
