Alex Lorenz a15d888abf MIR Serialization: Connect the machine function analysis pass to the MIR parser.
This commit connects the machine function analysis pass (which creates machine
functions) to the MIR parser, which will initialize the machine functions 
with the state from the MIR file and reconstruct the machine IR.

This commit introduces a new interface called 'MachineFunctionInitializer',
which can be used to provide custom initialization for the machine functions.

This commit also introduces a new diagnostic class called 
'DiagnosticInfoMIRParser' which is used for MIR parsing errors.
This commit modifies the default diagnostic handling in LLVMContext - now the
the diagnostics are printed directly into llvm::errs() so that the MIR parsing 
errors can be printed with colours.
