Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Armando Montanez 4cc2113114 [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.

Armando Montanez 6d6ff2e0d7 [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.

Armando Montanez e353459549 [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.

Sam Clegg 992fc88111 [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"

Armando Montanez c9488e4d89 Revert "[llvm-tapi] Don't override SequenceTraits for std::string"
Revert r348551 since it triggered some warnings that don't appear to have a quick fix.

Armando Montanez 8c1cd213b7 [llvm-tapi] Don't override SequenceTraits for std::string
Change the ELF YAML implementation of TextAPI so NeededLibs uses flow
sequence vector correctly instead of overriding the YAML implementation
for std::vector<std::string>>.

This should fix the test failure with the LLVM_LINK_LLVM_DYLIB build mentioned in D55381.

Still passes existing tests that cover this.

Armando Montanez 1e4b3709bb [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
