3995aa63f6 [TextAPI][elfabi] Fix failing tests from D56020

ec2e0f9305 [TextAPI][elfabi] Fix YAML support for weak symbols
Weak symbols are supposed to be supported in the ELF TextAPI
implementation, but the YAML handler didn't read or write the `Weak`
member of ELFSymbol. This change adds the YAML mapping and updates tests
to ensure correct behavior.

0665736292 [TextAPI][elfabi] Make SoName optional
This change makes DT_SONAME treated as an optional trait for ELF TextAPI
stubs. This change accounts for the fact that shared objects aren't
guaranteed to have a DT_SONAME entry. Tests have been updated to check
for correct behavior of an optional soname.

01342484a4 [TextAPI][elfabi] Make TBE handlers functions that return Errors
Since TBEHandler doesn't maintain state or otherwise have any need to be
a class right now, the read and write functions have been moved out and
turned into standalone functions. Additionally, the TBE read function
has been updated to return an Expected value for better error handling.
Tests have been updated to reflect these changes.

a97d9f8bb5 [llvm-tapi] Don't try to override SequenceTraits for std::string
For some reason this doesn't seem to work with LLVM_LINK_LLVM_DYLIB
build.

See https://logs.chromium.org/logs/chromium/bb/client.wasm.llvm/linux/37764/+/recipes/steps/LLVM_regression_tests/0/stdout

What is more it seems that overriding these traits for core types
(including std::string) is not supported/recommend by YAMLTraits.h.
See line 1918 which has the assertion:
 "only use LLVM_YAML_IS_SEQUENCE_VECTOR for types you control"

bab257c102 [llvm-tapi] initial commit, supports ELF text stubs
http://lists.llvm.org/pipermail/llvm-dev/2018-September/126472.html

TextAPI is a library and accompanying tool that allows conversion between binary shared object stubs and textual counterparts. The motivations and uses cases for this are explained thoroughly in the llvm-dev proposal [1]. This initial commit proposes a potential structure for the TAPI library, also including support for reading/writing text-based ELF stubs (.tbe) in addition to preliminary support for reading binary ELF files. The goal for this patch is to ensure the project architecture appropriately welcomes integration of Mach-O stubbing from Apple's TAPI [2].

Added:

 - TextAPI library
 - .tbe read support
 - .tbe write (to raw_ostream) support
