This change reorganize the register read/write code inside lldb-server on Linux
with moving the architecture independent code into a new class called
NativeRegisterContextLinux and all of the architecture dependent code into the
appropriate NativeRegisterContextLinux_* class. As part of it the compilation of
the architecture specific register contexts are only compiled on the specific
architecture because they can't be used in other cases.
The purpose of this change is to remove a lot of duplicated code from the different
register contexts and to remove the architecture dependent codes from the global
NativeProcessLinux class.

Previously, subtarget features were a bitfield with the underlying type being uint64_t.
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.
The first several times this was committed (e.g. r229831, r233055), it caused several buildbot failures.
Apparently the reason for most failures was both clang and gcc's inability to deal with large numbers (> 10K) of bitset constructor calls in tablegen-generated initializers of instruction info tables.
This should now be fixed.

Summary:
Following on from r209907 which made personality encodings indirect, do the
same for TType encodings. This fixes the case where a try/catch block needs
to generate references to, for example, std::exception in the
.gcc_except_table.
This commit uses DW_EH_PE_sdata8 for N64 as far as is possible at the moment.
However, it is possible to end up with DW_EH_PE_sdata4 when a TargetMachine is
not available. There's no risk of issues with inconsistency here since the
tables are self describing but it does mean there is a small chance of the
PC-relative offset being out of range for particularly large programs.

The old code had a bug if the description was between 75 and 85 characters or so as it substracted PSLen from Desc.size() instead of MAX_LINE_LEN in the compare. It also calculated odd values for PosE on the last split and just let StringRef::slice take care of it being larger than the description string.

I think the fact that it was explicitly excluding 0 kept this from being a tautology. The exclusion of 0 for the old math was also a bug that's easily hit if the description gets split into multiple lines.

instead of BinPackParameters. Braced lists are used as constructor
calls in many places and so the bin-packing should follow what is done
for other calls and not what is done for function declarations.

Specifically, don't add a space before it.
Before:
someFunction(... a);
var x = [1, 2, ... a];
After:
someFunction(...a);
var x = [1, 2, ...a];

This fixes a case where the column limit was incorrectly calculated
leading to a macro like this:
#define A \
[] { \
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx( \
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx); \
}
exceeding the column limit.

If binding to port 0 is selected, the actual port is printed.
This improves the reliability of platform startup by ensuring that
a free port can be found.
TEST PLAN
./lldb-server platform --listen *:0
Listening for a connection from <port-number>...
Will appear on stdout (with other stuff potentially)

Summary:
In case of functions that have a pointer argument and only pass it to
each other, the function attributes pass deduces that the pointer should
get the readnone attribute, but fails to remove a readonly attribute
that may already have been present.
