* Include whether functions are inlinable as they impact whether to add

* Fix how clang arguments got passed along, previously spacing was
passed along to CC1 causing search path inputs to look non-existent.
ObjCInterfaceRecords roughly align to the objc-classes key in tbd-files.
They condensely represent up to 3 symbols. The problem here is that when
represented this way, we lose granularity when these symbols could have
different linkages or outright don't exist. This can happen frequently
in interoptable code generated by the swift compiler. This adds fields
and utility functions to express unique properties for these symbols. If
the record does represent the same properties across all of its symbols,
it will be treated the same in the TBD. Otherwise it will be printed in
global's section.

A distinction that doesn't _usually_ matter is that the
MachO::SymbolKind is really a mapping of entries in TBD files not
symbols. To better understand this, rename the enum so it represents an
encoding mapped to TBDs as opposed to symbols alone.
For example, it can be a bit confusing that "GlobalSymbol" is a enum
value when all of those values can represent a GlobalSymbol.
`Record`'s hold target triple specific information about APIs and
symbols. This holds information about the relationship between ObjC
symbols and their linkage properties. It will be used to compare and run
significant operations between the frontend representation of symbols in
AST and symbol information extracted from Mach-O binaries. This differs
from the lighter weight Symbol and SymbolSet class where they are
deduplicated across targets and only represent exported symbols, that
class is mostly used for serializing.
Both Swift & LLD use TextAPI reader/writer apis to interface with TBD
files. Add doc strings to document what each API does. Also, add
shortcut APIs for validating input is a TBD file.
This reduces the differences between downstream and how tapi calls into
these APIs.
There are missing include and using in TextStubTests and
AsmPrinterDwarfTest and they causes build failures when using vanilla
GoogleTest v1.14.0. This patch fixes this issue.
TBD files now record minimum deplyoment versions and tapi interfaces
with apple system linker by a packed version encoding. Support mapping
between that and `VersionTuple`s.
This adds a new optional flag sim_support which is the same as
MH_SIM_SUPPORT in the MachO header.

The minOS version is recorded in tbd-v5 so the linker can report
diagnostics when a library and client are misconfigured.
Dylibs should always have a minOS recorded, but in was not recorded in
previous TBD versions. To accommodate the format transition, treat
unrecorded minOS versions as 0.

UUID's & `installapi` flag are no longer useful in recent apple linker/tapi.
The reason for removing them is that these are attributes that record
how a library was built but not really about the library itself. TBD
files now only track information this is important as link time
dependencies.

SymbolSet is a structure that acts as a simple container class for exported symbols that
belong to a library interface. It allows tapi to decouple the globals
from the other library attributes. It's uniqued by symbol name and `kind`, which all contain their assigned target triples.

Sometimes the clang driver will receive a target triple where the
deployment version is too low to support the platform + arch. In those
cases, the compiler upgrades the final minOS which is what gets recorded
ultimately by the linker in LC_BUILD_VERSION. TextAPI should also reuse
this logic for capturing minOS in recorded TBDv5 files.

Create writer for new JSON format.
The new JSON format allows practically all attributes to be defined per
target in a universal library however the internal representation only
allows one for the time being. For now the write will always write those
attributes as default available for all targets (install name,
compatability & current version, swift abi, flags e.g. flatnamepace &

Summary:

* this patch adds reader/writer support for MachO tbd files.
The usecase is to represent reexported libraries in top level library
that won't need to exist for linker indirection because all of the
needed content will be inlined in the same document.
