Fix Windows unwind info for functions in sections other than .text Previously we assumed the section name had the form .text$foo, which is what we used to do for inline functions. If the dollar wasn't present, we'd put unwind data in the .pdata and .xdata sections for the main .text section, which is incorrect. Fixes PR22001. llvm-svn: 224738

[MC] Create unique .pdata sections for every .text section Summary: This adds a unique ID to the COFF section uniquing map, similar to the one we have for ELF. The unique id is not currently exposed via the assembler because we don't have a use case for it yet. Users generally create .pdata with the .seh_* family of directives, and the assembler internally needs to produce .pdata and .xdata sections corresponding to the code section. The association between .text sections and the assembler-created .xdata and .pdata sections is maintained as an ID field of MCSectionCOFF. The CFI-related sections are created with the given unique ID, so if more code is added to the same text section, we can find and reuse the CFI sections that were already created.

[llvm-readobj] Update tests because of changes in llvm-readobj behavior This patch updates tests using llvm-readobj and llvm-readelf, because soon reading from stdin will be achievable only via a '-' as described here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to llvm-readobj behavior is here: https://reviews.llvm.org/D83704 Differential Revision: https://reviews.llvm.org/D83912 Reviewed by: jhenderson, MaskRay, grimar
