Summary: This allows to remove `using namespace llvm;` in those *.cpp files
When we want to revisit the decision (everything resides in llvm::mca::*) in the future, we can move things to a nested namespace of llvm::mca::, to conceptually make them separate from the rest of llvm::mca::*

Added begin()/end() methods to allow the usage of SourceMgr in foreach loops.
With this change, method getMCInstFromIndex() (as well as a couple of other
methods) are now redundant, and can be removed from the public interface.

and resource quantities.
Summary:
This patch removes the storing of accumulated floating point data
within the llvm-mca library.
This patch splits-up the two quantities: cycles and number of resource units.
By splitting-up these two quantities, we delay the calculation of "cycles per resource unit"
until that value is read, reducing the chance of accumulating floating point error.
I considered using the APFloat, but after measuring performance, for a large (many iteration)
sample, I decided to go with this faster solution.
