Thomas Preud'homme 0726cb0047 [FileCheck, 3/4] Allow AP value for numeric expressions ...

Use APInt to represent numeric variables and expressions, therefore
removing overflow concerns. Only remains underflow when the format of an
expression is unsigned (incl. hex values) but the result is negative.
Note that this can only happen when substituting an expression, not when
capturing since the regex used to capture unsigned value will not include
minus sign, hence all the code removal for match propagation testing.
This is what this patch implement.
