This patch renames the "Initial" member of WasmLimits to the name used
in the spec, "Minimum".
In the core WebAssembly specification, the Limits data type has one
required "min" member and one optional "max" member, indicating the
minimum required size of the corresponding table or memory, and the
maximum size, if any.
Although the WebAssembly spec does instantiate locally-defined tables
and memories with the initial size being equal to the minimum size, it
can't impose such a requirement for imports. It doesn't make sense to
require an initial size for a memory import, for example. The compiler
can only sensibly express the minimum and maximum sizes.
See
https://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md#naming-of-size-limits
for a related discussion that agrees that the right name of "initial" is
"minimum" when querying the type of a table or memory from JavaScript.
(Of course it still makes sense for JS to speak in terms of an initial
size when it explicitly instantiates memories and tables.)

Adds more testing in basic-assembly.s and a new test tables.s.
Adds support to yaml reading and writing of tables as well.

The `sections-ext.test` is a test for ELF that is used
to test `--st`, `--sr` and `--sd` extension options for `-S`.
There are 2 problems with it:
1) It is broken, because for CHECK lines it contains there is
no corresponding `FileCheck` call.
2) It uses the precompiled object: `trivial.obj.elf-i386`.
This is the last ELF test where `trivial.obj.elf-i386` is used so we can get
rid of the binary and use an YAML description.
Also, there is a `Inputs/trivial.ll` file that describes how `trivial*` objects
in `Inputs` folders are created. I've removed it from `ELF`, because it is not
actual anymore (we have no more input binaries created with the use of trivial.ll there)
and copied the refined versions of it to `COFF`, `MachO` and `wasm` Input folders.

The changes the in-memory representation of wasm symbols such that their
optional ImportName and ImportModule use llvm::Optional.
ImportName is set whenever WASM_SYMBOL_EXPLICIT_NAME flag is set.
ImportModule (for imports) is currently always set since it defaults to
"env".
In the future we can possibly extent to binary format distingish
import which have explit module names.

tools/llvm-readobj currently contains tests that are either general for
all file types or that mix file types inside. This patch refactors
these test and leaves only general tests in that folder. All other
tests were moved to ELF/COFF/MachO and wasm accordingly.
I tried to minimize amount of changes, so most of the test parts
remained unchanged. Any further refactorings and improvements for
particular tests should be done independently from this patch.

This creates the next subfolders in the test directory:
"COFF", "ELF", "MachO", "wasm".
I've also removed platform specific prefixes, like "coff-*".
One unused binary was removed as well: `Inputs/relocs.obj.elf-mips`
