6d6a041983 [RISCV] Recognize new relocation types
This patch adds all RISC-V relocation types, as of binutils 2.29. Note that 
R_RISCV32_PCREL is not currently documented in the RISC-V ELF PSABI.

c9c28d96fa [WebAssembly] Expose the offset of each data segment
Summary:
This allows tools like lld that process relocations
to apply data relocation correctly. This information
is required because relocation are stored as section
offset.

Revert "Revert "Revert "Revert "Replace trivial use of external rc.exe by writing our own .res file.""""

This reverts commit 61a90a67ed54a1f0dfeab457b65abffa129569e4.

The patches were intially reverted because they were causing a failure
on CrWinClangLLD.  Unfortunately, this was done haphazardly and didn't
compile, so the revert was reverted again quickly to fix this.  One that
was done, the revert of the revert was itself reverted.  This allowed me
to finally fix the actual bug in r307452.  This patch re-enables the
code path that had originally been causing the bug, now that it (should)
be fixed.

This reverts commit 5fecbbbe5049665d86834cf69d8f75db4f392308.

The initial revert was done in order to prevent ongoing errors on
chromium bots such as CrWinClangLLD.  However, this was done haphazardly
and I didn't realize there were test and compilation failures, so this
revert was reverted.  Now that those have been fixed, we can revert the
revert of the revert.

Summary:
This reverts commit 51931072a7c9a52540baf76fc30ef391d2529a2f.

This revert was originally done because the integrations of the new
WindowsResource library into LLD was causing error in chromium, due to
bugs in how resource sections were handled.  These bugs were fixed,
meaning that the features may be reintegrated.

7eed73772d [DWARF] Added verification checks for the .apple_names section.
This patch verifies the number of atoms, the validity of the form for each atom, as well as the validity of the
hashdata. For hashdata, we're verifying that the hashdata offset is correct and that the offset in the .debug_info for
each DIE in the hashdata is also valid.

This reverts commit d4c7e9fc63c10dbab0c30186ef8575474a704496.

This is done in order to address the failure of CrWinClangLLD etc. bots.
These throw an error of "side-by-side configuration is incorrect" during
compilation, which sounds suspiciously related to these manifest
changes.

69e4d36881 Replace trivial use of external rc.exe by writing our own .res file.
This patch removes the dependency on the external rc.exe tool by writing
a simple .res file using our own library. In this patch I also added an
explicit definition for the .res file magic.  Furthermore, I added a
unittest for embeded manifests and fixed a bug exposed by the test.

3fe8da4e8c Change llvm-nm for Mach-O files to use dyld info in some cases when printing symbols.
In order to reduce swift binary sizes, Apple is now stripping swift symbols
from the nlist symbol table.  llvm-nm currently only looks at the nlist symbol
table and misses symbols that are present in dyld info.   This makes it hard to
know the set of symbols for a binary using just llvm-nm.  Unless you know to
run llvm-objdump -exports-trie that can output the exported symbols in the dyld
info from the export trie, which does so but in a different format.

Also moving forward the time may come a when a fully linked Mach-O file that
uses dyld will no longer have an nlist symbol table to avoid duplicating the
symbol information.

This change adds three flags to llvm-nm, -add-dyldinfo, -no-dyldinfo, and
-dyldinfo-only.

The first, -add-dyldinfo, has the same effect as when the new bit in the Mach-O
header, MH_NLIST_OUTOFSYNC_WITH_DYLDINFO, appears in a binary.  In that it
looks through the dyld info from the export trie and adds symbols to be printed
that are not already in its internal SymbolList variable.  The -no-dyldinfo
option turns this behavior off.

The -dyldinfo-only option only looks at the dyld information and recreates the
symbol table from the dyld info from the export trie and binding information.
As if it the Mach-O file had no nlist symbol table.

Also fixed a few bugs with Mach-O N_INDR symbols not correctly printing the
indirect name, or in the same format as the old nm-classic program.
