[PATCH] D53725: [CodeGen] Move `emitConstant` from ScalarExprEmitter to CodeGenFunction. NFC.

[Volodymyr Sapsai via Phabricator via cfe-commits]

vsapsai created this revision.
vsapsai added reviewers: rjmccall, ahatanak.
Herald added a subscriber: dexonsmith.

The goal is to use `emitConstant` in more places. Didn't move
`ComplexExprEmitter::emitConstant` because it returns a different type.
