Easwaran Raman 695890c971 Attach maximum function count to Module when using PGO mode.
This sets the maximum entry count among all functions in the program to the module using module flags. This allows the optimizer to use this information.

README

These are tests for instrumentation based profiling.  This specifically means
the -fprofile-instr-generate and -fprofile-instr-use driver flags.

Tests in this directory should usually test both:

  - the generation of instrumentation (-fprofile-instr-generate), and
  - the use of profile data from instrumented runs (-fprofile-instr-use).

In order to test -fprofile-instr-use without actually running an instrumented
program, .profdata files are checked into Inputs/.

The input source files must include a main function such that building with
-fprofile-instr-generate and running the resulting program generates the same
.profdata file that is consumed by the tests for -fprofile-instr-use.  Even
tests that only check -fprofile-instr-use should include such a main function,
so that profile data can be regenerated as the .profdata file format evolves.
