BlockFrequencyInfoImpl: Avoid big numbers, increase precision for small spreads
BlockFrequencyInfo calculates block frequencies as Scaled64 numbers but as a last step converts them to unsigned 64bit
BlockFrequencyInfoImpl: Avoid big numbers, increase precision for small spreads
BlockFrequencyInfo calculates block frequencies as Scaled64 numbers but as a last step converts them to unsigned 64bit integers (`BlockFrequency`). This improves the factors picked for this conversion so that:
* Avoid big numbers close to UINT64_MAX to avoid users overflowing/saturating when adding multiply frequencies together or when multiplying with integers. This leaves the topmost 10 bits unused to allow for some room.
* Spread the difference between hottest/coldest block as much as possible to increase precision.
* If the hot/cold spread cannot be represented loose precision at the lower end, but keep the frequencies at the upper end for hot blocks differentiable.

[llvm-cov gcov] Compute unmeasured arc counts by Kirchhoff's circuit law
For a CFG G=(V,E), Knuth describes that by Kirchoff's circuit law, the minimum
number of counters necessary is |E|-(|V|-1). The emitted edges form a spanning
tree. libgcov emitted .gcda files leverages this optimization while clang
--coverage's doesn't.
Propagate counts by Kirchhoff's circuit law so that llvm-cov gcov can
correctly print line counts of gcc --coverage emitted files and enable
the future improvement of clang --coverage.

[InstrProf] Port test suite to Windows
Summary:
Before this change, check-profile would run, but all tests would be
marked unsupported on Windows. This is the new status of 'check-profile'
after this change:
Testing Time: 6.66s
Expected Passes : 29
Expected Failures : 5
Unsupported Tests : 39
I moved many tests that exercise posix-y features like dlopen and DSOs
into the Posix subdirectory, and ran the tests on Linux to validate my
changes.
These are the remaining tests that I handled on a case by case basis:
- instrprof-path.c
Passes, Fixed some path portability issues
- instrprof-gcov-exceptions.test
Passes, the FileCheck actually succeeds on Windows, so I RUNX'd it
- instrprof-icall-promo.test
XFAILed, probably due to C++ ABI differences in vtables
- instrprof-merge-match.test
- instrprof-merge.c
- instrprof-merging.cpp
XFAILed, These seem like real bugs that need fixing
- instrprof-version-mismatch.c
XFAILed, Overriding the weak version symbol doesn't work
- instrprof-without-libc.c
UNSUPPORTED, test needs an executable symbol table, Windows has none
