  [TableGen][GlobalISel] Fix tblgen optimization bug

When optimizing the table, PointerToAnyOperandMatchers would be
incorrectly reported as identical even though they have different
SizeInBits values. This bug was due to failing to overload the
isIdentical() method, which this patch addresses.

  [GlobalISel] Fix and tidy up documentation for ValueMapping class (NFC)

The documentation was missing a '*/' in '/*<2x32-bit> vadd {0, 64, VPR}',
and the example code are now aligned to improve readability.
