Symlinks are poorly supported in Bazel+remote-exec. Create the links from `ld.lld`,
`ld64.lld`, `lld-link`, `wasm-ld` to `lld` using LLVM's `binary_alias` instead.

Also a new pass option `ConvertToLLVMPass` to populate only patterns from the specified dialects. This is needed because the existing test cases expect that only ops from certain dialects are lowered. (E.g., "arith-to-llvm" expects that only "arith" ops are lowered but not "func" ops.)

This revision adds a `transform.apply_conversion_patterns.func.func_to_llvm` transformation.
It is unclear at this point whether this should be spelled out as a standalone transformation
or whether it should resemble `transform.apply_conversion_patterns.dialect_to_llvm "fun"`.
This is dependent on how we want to handle the type converter creation.
In particular the current implementation exhibits the fact that
`transform.apply_conversion_patterns.memref.memref_to_llvm_type_converter` was not rich enough
and did not match the LowerToLLVMOptions.
Keeping those options in sync across all the passes that lower to LLVM is very error prone.
Instead, we should have a single `to_llvm_type_converter`.

Three different options can be specified:
* `bufferization.copy_tensor` (default)
* `linalg.copy`
* `none` (no copy_back)

This op populates conversion patterns by querying the
ConvertToLLVMPatternInterface. Only dialects that support this interface
are supported.
Differential Revision: https://reviews.llvm.org/D157487
These patterns are exposed via a new "apply_conversion_patterns" op.
Also provide a new type converter that converts from memref to LLVM types. Conversion patterns that lower to LLVM are special: they require an `LLVMTypeConverter`; a normal `TypeConverter` is not enough. This revision also adds a new interface method to pattern descriptor ops to verify that the default type converter of the enclosing "apply_conversion_patterns" op is compatible with the set of patterns. At the moment, a simple `StringRef` is used. This can evolve to a richer type in the future if needed.

This patch is an alternative to D155902. It provides the following benefits:
- No buffer manual allocation and error handling for the general case
- More flexible API : width specifier, sign and prefix handling
- Simpler code
The more flexible API removes the need for manually tweaking the buffer afterwards, and so prevents relying on implementation details of IntegerToString.

This patch is large, but is almost entirely just adding casts to calls
to syscall_impl. Much of the work was done programatically, with human
checking when the syntax or types got confusing.
