CodeGen: Synthesize "float-abi" module flag from -float-abi

Avoid annoying test updates when the corresponding TargetOptions
field is removed. Make the -float-abi llc/opt option a lit test
convenience that records the floating-point ABI in the IR,
mirroring how -mcpu/-mattr are recorded as function attributes.

CodeGen: Remove TargetOptions::FloatABIType

This is now fully replaced with the "float-abi" module flag.
If the module flag is not present, the default is computed
from the triple. Consumers are updated to read the module flag.

RuntimeLibraryAnalysis now defers analysis until run() on a Module,
instead of during the pass constructor as before. This requires copying
all of the remaining relevant TargetOptions so they are available
when the module is seen.

Unfortunately, ARM still depends on TargetOptions for determining
the float-abi. -target-abi=aapcs16 still changes the default float-abi,
but an explicit module flag wins.
