Support arbitrary address space pointers in masked gather/scatter intrinsics

[eladcohen]

Summary

Fixes PR31789 - When loop-vectorize tries to use these intrinsics for a non-default address space pointer we fail with a "Calling a function with a bad signature!" assertion. This patch tries to solve this by adding the 'vector of pointers' argument as an overloaded type which will determine the address space.

I suggest to keep the standard (or close to standard) Argument_Info structure and access it though functions.

Fixed Elena's comments.

I might have missed something, but all the examples in the langref and test-cases include only pointers to addspace(0). Maybe change/add tests and example to include non-zero address-spaces?

I have added new test-cases in test/Transforms/LoopVectorize/X86/gather_scatter.ll to check that the Loop Vectorizer can successfully create scatter/gather instructions for pointers in the non-default address space.
I'll add non-default address space examples to the langref - thanks!

This is one more place where I suggest to replace the hardcoded "shift" with a method.

 Conversion Operations
 ---------------------
 
 The instructions in this category are the conversion instructions
 (casting) which all take a single operand and a type. They perform
 various bit conversions on the operand.

 This is an overloaded intrinsic. The loaded data are multiple scalar values of any integer, floating point or pointer data type gathered together into one vector.

 Overview:
 """""""""
 
 Reads scalar values from arbitrary memory locations and gathers them into one vector. The memory locations are provided in the vector of pointers '``ptrs``'. The memory is accessed according to the provided mask. The mask holds a bit for each vector lane, and is used to prevent memory accesses to the masked-off lanes. The masked-off lanes in the result vector are taken from the corresponding lanes of the '``passthru``' operand.
 
 
 Arguments:
 """"""""""
 
 The first operand is a vector of pointers which holds all memory addresses to read. The second operand is an alignment of the source addresses. It must be a constant integer value. The third operand, mask, is a vector of boolean values with the same number of elements as the return type. The fourth is a pass-through value that is used to fill the masked-off lanes of the result. The return type, underlying type of the vector of pointers and the type of the '``passthru``' operand are the same vector types.
 
 
 Semantics:
 """"""""""
 
 The '``llvm.masked.gather``' intrinsic is designed for conditional reading of multiple scalar values from arbitrary memory locations in a single IR operation. It is useful for targets that support vector masked gathers and allows vectorizing basic blocks with data and control divergence. Other targets may support this intrinsic differently, for example by lowering it into a sequence of scalar load operations.
 The semantics of this operation are equivalent to a sequence of conditional scalar loads with subsequent gathering all loaded values into a single vector. The mask restricts memory access to certain lanes and facilitates vectorization of predicated basic blocks.

 Writes each element from the value vector to the corresponding memory address. The memory addresses are represented as a vector of pointers. Writing is done according to the provided mask. The mask holds a bit for each vector lane, and is used to prevent memory accesses to the masked-off lanes.
 
 Arguments:
 """"""""""
 
 The first operand is a vector value to be written to memory. The second operand is a vector of pointers, pointing to where the value elements should be stored. It has the same underlying type as the value operand. The third operand is an alignment of the destination addresses. The fourth operand, mask, is a vector of boolean values. The types of the mask and the value operand must have the same number of vector elements.
 
 
 Semantics:
 """"""""""
 
 The '``llvm.masked.scatter``' intrinsics is designed for writing selected vector elements to arbitrary memory addresses in a single IR operation. The operation may be conditional, when not all bits in the mask are switched on. It is useful for targets that support vector masked scatter and allows vectorizing basic blocks with data and control divergence. Other targets may support this intrinsic differently, for example by lowering it into a sequence of branches that guard scalar store operations.
