Easwaran Raman 71069cf67d Use ProfileSummaryInfo in inline cost analysis.
Instead of directly using MaxFunctionCount and function entry count to determine callee hotness, use the isHotFunction/isColdFunction methods provided by ProfileSummaryInfo.

Eric Liu d09f15ea6f Revert "Replace the use of MaxFunctionCount module flag"
This reverts commit r266477.

This commit introduces cyclic dependency. This commit has "Analysis" depend on "ProfileData",
while "ProfileData" depends on "Object", which depends on "BitCode", which
depends on "Analysis".

Easwaran Raman bdb6f1dcc3 Determine callee's hotness and adjust threshold based on that. NFC.
This uses the same criteria used in CFE's CodeGenPGO to identify hot and cold
callees and uses values of inlinehint-threshold and inlinecold-threshold
respectively as the thresholds for such callees.
