For assigning SourceLocations to macro arg tokens, reserve a single SLocEntry

for tokens that are lexed consecutively from the same FileID, instead of creating
a SLocEntry for each token. e.g for

   assert(foo == bar);

there will be a single SLocEntry for the "foo == bar" chunk and locations
for the 'foo', '==', 'bar' tokens will point inside that chunk.

For parsing SemaExpr.cpp, this reduced the number of SLocEntries by 25%.
