This fixes the https://bugs.llvm.org/show_bug.cgi?id=41355.
Previously with -r we printed relocation section name instead of the target section name.
It was like this: "RELOCATION RECORDS FOR [.rel.text]"
Now it is: "RELOCATION RECORDS FOR [.text]"
Also when relocation target section has more than one relocation section,
we did not combine the output. Now we do.

We use both -long-option and --long-option in tests. Switch to --long-option for consistency.
In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf.
While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf).

This value is the first vector instruction type in numerical order. The
previous value was incorrect, leaving TypeCVI_GATHER outside of the range
for vector instructions. This caused vector .new instructions to be
incorrectly encoded in the presence of gather.

Data directives such as .word, .half, .hword are currently parsed using
HexagonAsmParser::ParseDirectiveValue which effectively duplicates logic from
AsmParser::parseDirectiveValue. This patch deletes that duplicated logic in
favour of using addAliasForDirective.

Change relocation output so that relocation information follows
individual instructions rather than clustering them at the end
of packets.
This change required shifting block of code but the actual change
is in HexagonPrettyPrinter's PrintInst.

HexagonGenMux would collapse pairs of predicated transfers if it assumed
that the predicated .new forms cannot be created. Turns out that generating
mux is preferable in almost all cases.
Introduce an option -hexagon-gen-mux-threshold that controls the minimum
distance between the instruction defining the predicate and the later of
the two transfers. If the distance is closer than the threshold, mux will
not be generated. Set the threshold to 0 by default.

This patch lets the llvm tools handle the new HVX target features that
are added by frontend (clang). The target-features are of the form
"hvx-length64b" for 64 Byte HVX mode, "hvx-length128b" for 128 Byte mode HVX.
"hvx-double" is an alias to "hvx-length128b" and is soon will be deprecated.
The hvx version target feature is upgated form "+hvx" to "+hvxv{version_number}.
Eg: "+hvxv62"
For the correct HVX code generation, the user must use the following
target features.
For 64B mode: "+hvxv62" "+hvx-length64b"
For 128B mode: "+hvxv62" "+hvx-length128b"
Clang picks a default length if none is specified. If for some reason,
no hvx-length is specified to llvm, the compilation will bail out.
There is a corresponding clang patch.

- Updates to the handling of certain relocations.
- Better handling of duplex instructions.

The -mattr options in these four tests have no effect on the output of
llvm-objdump. In the case of the two Mips tests, removing the -mattr option
left duplicate RUN lines so the duplicates have been removed.
