[compiler-rt] Add ConsumeProbability and ConsumeFloatingPoint methods to FDP.
Summary:
Also slightly cleaned up the comments and changed the header's extension
back to `.h` as per comments on https://reviews.llvm.org/D65812.
New methods added:
* `ConsumeProbability` returns [0.0, 1.0] by consuming an unsigned integer value
from the input data and dividing that value by the integer's max value.
* `ConsumeFloatingPointInRange` returns a floating point value in the given
range. Relies on `ConsumeProbability` method. This method does not have the
limitation of `std::uniform_real_distribution` that requires the given range
to be <= the floating point type's max. If the range is too large, this
implementation will additionally call `ConsumeBool` to decide whether the
result will be in the first or the second half of the range.
* `ConsumeFloatingPoint` returns a floating point value in the range
`[std::numeric_limits<T>::lowest(), std::numeric_limits<T>::min()]`.
Tested on Linux, Mac, Windows.
