[llvm] Reduce ComplexDeinterleavingPass.h includes

Remove the unnecessary `"llvm/IR/PatternMatch.h"` include directive from

file

[llvm] Reduce ComplexDeinterleavingPass.h includes

Remove the unnecessary `"llvm/IR/PatternMatch.h"` include directive from
`ComplexDeinterleavingPass.h` and move it to the corresponding source
file.

Add missing includes that were transitively included by this header to 2
other source files.

This reduces the total number of preprocessing tokens across the LLVM
source files in `lib` from (roughly) 1,964,876,961 to 1,935,091,611 - a
reduction of ~1.52%. This should result in a small improvement in
compilation time.

[CodeGen] Enable processing of interconnected complex number operations

With this patch, ComplexDeinterleavingPass now has the ability to handle
any number of interconnected operations involving complex numbers.
For example, the patch enables the processing of code like the following:

for (int i = 0; i < 1000; ++i) {
a[i] = w[i] * v[i];
b[i] = w[i] * u[i];
}

This code has multiple arrays containing complex numbers and a common
subexpression `w` that appears in two expressions.
