FileCheck [8/12]: Define numeric var from expr
Summary: This patch is part of a patch series to add support for FileCheck numeric expressions. This specific patch lift the restriction for a numeric expression to either be a variable definition or a numeric expression to try to match. This commit allows a numeric variable to be set to the result of the evaluation of a numeric expression after it has been matched successfully. When it happens, the variable is allowed to be used on the same line since its value is known at match time. It also makes use of this possibility to reuse the parsing code to parse a command-line definition by crafting a mirror string of the -D option with the equal sign replaced by a colon sign, e.g. for option '-D#NUMVAL=10' it creates the string '-D#NUMVAL=10 (parsed as [[#NUMVAL:10]])' where the numeric expression is parsed to define NUMVAL. This result in a few tests needing updating for the location diagnostics on top of the tests for the new feature. It also enables empty numeric expression which match any number without defining a variable. This is done here rather than in commit #5 of the patch series because it requires to dissociate automatic regex insertion in RegExStr from variable definition which would make commit #5 even bigger than it already is.

The syntax also supports an empty expression, equivalent to writing {{[0-9]+}},

A numeric variable can also be defined to the result of a numeric expression,

The ``--enable-var-scope`` option has the same effect on numeric variables as
