[test] Use yaml2obj -o %t instead of > %t To improve consistency and avoid unneeded shell feature (output redirection). While here, make other changes to improve consistency --docnum 1 => --docnum=1 -docnum=x => --docnum=x

[elfabi] Add support for reading DT_SONAME from binaries This change gives the llvm-elfabi tool the ability to read DT_SONAME from a binary ELF file into an ELFStub. Added: - DynamicEntries struct for storing dynamic entries that are relevant to elfabi. - terminatedSubstr() retrieves a null-terminated substring from a StringRef. - appendToError() appends a string to an error, allowing more specific error messages. Differential Revision: https://reviews.llvm.org/D55629 llvm-svn: 351361

ProgramHeaders:
[yaml2obj] - ProgramHeaders: introduce FirstSec/LastSec instead of Sections list. Imagine we have a YAML declaration of few sections: `foo1`, `<unnamed 2>`, `foo3`, `foo4`. To put them into segment we can do (1*): ``` Sections: - Section: foo1 - Section: foo4 ``` or we can use (2*): ``` Sections: - Section: foo1 - Section: foo3 - Section: foo4 ``` or (3*) : ``` Sections: - Section: foo1 ## "(index 2)" here is a name that we automatically created for a unnamed section. - Section: (index 2) - Section: foo3 - Section: foo4 ``` It looks really confusing that we don't have to list all of sections. At first I've tried to make this rule stricter and report an error when there is a gap (i.e. when a section is included into segment, but not listed explicitly). This did not work perfect, because such approach conflicts with unnamed sections/fills (see (3*)). This patch drops "Sections" key and introduces 2 keys instead: `FirstSec` and `LastSec`. Both are optional. Differential revision: https://reviews.llvm.org/D90458

[Object/ELF.h] - Improve error reporting. The errors coming from ELF.h are usually not very useful because they are uninformative. This patch is a first step to improve the situation. I tested this patch with a run of check-llvm and found that few messages are untested. In this patch, I did not add more tests but marked all such cases with a "TODO" comment. For all tested messages I extended the error text to provide more details (see test cases changed). Differential revision: https://reviews.llvm.org/D64014 llvm-svn: 365183
