Subject: [PATCH 1/3] checkpatch: Find hex constants as a single IDENT

Hexadecimal values are current found in 2 parts.
A hex constant like 0x123456abcdef is found as
0 and then x123456abcdef and later coalesced.

Instead, reverse the order of the 2 searches in
$Constant to find 0x first, then 0 so that the
entire hex constant is found all at once.
