Vedant Kumar 0978def859 [GISel][RegBankSelect] Hide assertion failure from LLT::getScalarSizeInBits [2/14]
Summary:
It looks like RegBankSelect can try to assign a bank based on a
DBG_VALUE instead of ignoring it. This eventually leads to an assert
in AArch64RegisterBankInfo::getInstrMapping because there is some info
missing from the DBG_VALUE MachineOperand (I see: `Assertion failed:
(RawData != 0 && "Invalid Type"), function getScalarSizeInBits`).

I'm not 100% sure it's safe to insert DBG_VALUE instructions right
before RegBankSelect (that's what -debugify-and-strip-all-safe is
doing). Any advice appreciated.

Depends on D78135.
