Roman Tereshin b1ba127aa8 [GlobalISel][InstructionSelect] Moving type checks forward, perf patch 6 
This patch continues a series of patches started by r332907 (reapplied
as r332917)

In this commit we sort type checks towards the beginning of every rule
within the MatchTable as they fail often and it's best to fail early.

This is expected to decrease time GlobalISel spends in its
InstructionSelect pass by roughly 7% for an -O0 build as measured on
sqlite3-amalgamation (http://sqlite.org/download.html) targeting
AArch64. The amalgamation is a large single-file C-source that makes
compiler backend performance improvements to stand out from frontend.
It's also a part of CTMark.
