lupdate: Support numeric literal separators

Numeric literals that use apostrophes were introduced in C++14 so this
adds support for cases like:

int d = 10'000'00;
int x = 0xAF'FE;

This patch allows just any number and combination of apostrophes in
numeric literals and doesn't attempt to detect ill-formed literals.  We
assume, lupdate runs on code that has been accepted by a C++ compiler.
