Add clang frontend flags for machine profiles.

- `-fmachine-profile-generate`
  - Produce an instrumented binary
- `-fmachine-profile-function-coverage`
  - Only profile function coverage
- `-fmachine-profile-block-coverage`
  - Profile basic block coverage
- `-fmachine-profile-link-unit-name=`
  - Specify a name to identify the current link unit
- `-fno-machine-profile-runtime`
  - Do not link the MIP runtime
- `-fno-machine-profile-dump`
  - Do not dump the raw profile data when the program exits
- `-fmachine-profile-selected-function-group=`, `-fmachine-profile-function-group-count=`
  - Only instrument group `i` of `N` total groups of functions
- `-fmachine-profile-use=`
  - Use the provided profile for optimization
