[fir] Add fir.zero_bits conversion pattern to LLVM IR dialect 
This patch adds the ZeroOpConversion pattern to LLVM IR dialect.
Conversion of aggregate types is not implemented yet and will trigger a
failure to legalize the operation. This is tested in the
convert-to-llvm-invalid.fir test file.

This patch is part of the upstreaming effort from fir-dev branch.

[fir] Add base of the FIR to LLVM IR pass 
This patch adds the base of the FIR to LLVM IR Dialect conversion pass.
It currently can convert the following operations:
 - fir.global
 - fir.has_value
 - fir.address_of
 - fir.undefined

This patch is part of the upstreaming effort from fir-dev branch. It does not
cover all FIR operations in order to have small patches. Several patches will
follow to convert other operations.
