Haohai Wen 73f5f83b19 [BasicBlockSections] Using MBBSectionID as DenseMap key (#97295) ...

getSectionIDNum may return same value for two different MBBSectionID.
e.g. A Cold type MBBSectionID with number 0 and a Default type
MBBSectionID with number 2 get same value 2 from getSectionIDNum. This
may lead to overwrite of MBBSectionRanges.  Using MBBSectionID itself
as DenseMap key is better choice.
