Roman Tereshin a4c410d50d [GlobalISel][InstructionSelect] Switching over root LLTs, perf patch 10 
This patch continues a series of patches started by r332907 (reapplied
as r332917).

In this commit we introduce new matching opcode for the MatchTable:
GIM_SwitchType, similar to GIM_SwitchOpcode, and use it to switch over
LLTs of def operands of root instructions on the 2nd level of the
MatchTable within GIM_SwitchOpcode's cases.

This is expected to decrease time GlobalISel spends in its
InstructionSelect pass by about 6.5% for an -O0 build as measured on
sqlite3-amalgamation (http://sqlite.org/download.html) targeting
AArch64 (cross-compile on x86).
