MSP430: Enable relaxation of jump instructions to hard-coded pcrel offsets
This patch fixes execution failures which occur when the BR in a
sequence such as:
J<cond> 1f
BR
1:
is relaxed to a JMP, and the pc-relative offset for the destination of
the J<cond> instruction is hard-coded to be 2 words ahead of the
instruction.
The hard-coded offset will cause execution to jump 1 word ahead of where
it should actually go.
Instead we now detect the hard-coded offset is one we inserted earlier,
and invert the condition, allowing us to remove the BR entirely.

AArch64: Fix cfinv disassembly issues
This fixes the preferred disassembly for cfinv. The Armv8.4-a instruction
overlaps with the possible encoding space for msr. This because msr allows you
to use unallocated encoding space using the general sA_B_cC_cD_E form.
However when an encoding does become allocated then we need to ensure that it's
used as the preferred disassembly. The problem with cfinv is that its mask has
all bits sets because it has no arguments.
This causes issues for the Alias resolver in gas as it uses the mask to build
alias graph. In this case it can't do it since it thinks almost everything
would alias with cfinv. So instead we can only fix this by moving cfinv before
msr.

x86: VCVTNEPS2BF16{X,Y} should permit broadcasting
Just like other VCVT*{X,Y} templates do, and to allow the programmer
flexibility (might be relevant in particular when heavily macro-izing
code), the two templates should also have Broadcast set, just like their
X/Y-suffix-less counterparts. This in turn requires them to also have
* Dword set on their memory operands, to cover the logic added to
i386gen by 4a1b91eabbe7 ("x86: Expand Broadcast to 3 bits"),
* RegXMM/RegYMM set on their source operands, to satisfy broadcast
sizing logic in gas itself.
Otherwise ATTSyntax templates wouldn't need such operand size attributes.

The issue is that that '#include <config.h>' picks up bfd's config.h

This problem doesn't trigger in the gdb dir because there we generate
config.h under that exact name so gnulib's libc-config.h ends up
picking gdb's config.h instead of gnulib.c and that ends up harmless.
In gdbsupport, the config.h file is really named support-config.h, so
that '#include <config.h>' in libc-config.h doesn't pick it like it
would if it had the conventional config.h name.
This patch fixes it by simply renaming gdbserver's support-config.h to
config.h.

Support for DWARF5 location lists entries
This patch handles DW_LLE_base_addressx, DW_LLE_startx_length and
DW_LLE_start_length.
Tested by running the testsuite before and after the patch and there is
no increase in the number of test cases that fails. Tested with both
-gdwarf-4 and -gdwarf-5 flags. Also tested -gslit-dwarf along with
-gdwarf-4 as well as -gdwarf5 flags.

[binutils][arm] PR25376 Change MVE into a CORE_HIGH feature
This patch moves MVE feature bits into the CORE_HIGH section. This makes sure
.fpu and -mfpu does not reset the bits set by MVE. This is important because
.fpu has no option to "set" these same bits and thus, mimic'ing GCC, we choose
to define MVE as an architecture extension rather than put it together with
other the legacy fpu features.
This will enable the following behavior:
.arch armv8.1-m.main
.arch mve
.fpu fpv5-sp-d16 #does not disable mve.
vadd.i32 q0, q1, q2
This patch also makes sure MVE is not taken into account during auto-detect.
This was already the case, but because we moved the MVE bits to the
architecture feature space we must make sure ARM_ANY does not include MVE.

x86: VPEXTRQ/VPINSRQ are unavailable outside of 64-bit mode
The AVX512DQ patterns lacking a Cpu64 attribute made the memory operand
forms accepted even outside of 64-bit mode, and this even without any
{evex} pseudo-prefix (otherwise one could argue that this is an attempt
to follow one possible, albeit somewhat odd, interpretation of the SDM
wording to this effect).
For consistency between the various involved templates drop the
* (now) unnecessary IgnoreSize attributes
* unnecessary (due to VexW1) Size64 attributes from VEX encoded forms
* redundant (with Reg64) Qword operand attributes
uniformly.

texi2pod.pl: import support for @t{...} from gcc
GDB's man page source (in gdb.texinfo) contains:
@t{++}
The @t{...} part is supposed to display the wrapped text with a
fixed-width font. The texi2pod.pl script currently doesn't handle
@t{...}, so it appears as-is in the man page:
You can use GDB to debug programs written in C, C@t{++}, Fortran and Modula-2.
gcc's version of texi2pod.pl (at contrib/texi2pod.pl in gcc's repo)
replaces @t{...} with the wrapped text as-is, which I think is an
acceptable behavior. The fixed-width font distinction is not really
important for a man page, where the text will be displayed with whatever
font the user is using.
Import the line that does that from gcc's version.
I have verified that there is no other, unwanted change in man pages
generated in binutils' and GDB's doc, with this patch applied.

Use get_thread_regcache instead of get_current_regcache in post_create_inferior
In post_create_inferior, we get the current thread using the
inferior_thread function and store it in `thr`. We then call
get_current_regcache immediately after, which does:
return get_thread_regcache (inferior_thread ());
This patch makes post_create_inferior use get_thread_regcache, passing
`thr`, saving an unnecessary inferior_thread call.

tic4x disassembly static variables
tic4x uses a number of static variables for tables that are generated
depending on the current machine (tic4x vs. tic3x). However, it is
possible to change the machine from one invocation of print_insn_tic4x

and uses a relatively small known size array of register names rather
than a malloc'd table.
