Generate (at runtime) the table used to drive getSubRegFromChannel,

The is a step closer to it being staticly generated by TableGen and
allows getSubRegFromChannel handle all bitwidths in the mean time.

[clangd] Refine recoveryAST flags in clangd

so that we could start experiment for C.

Previously, these flags in clangd were only meaningful for C++. We need
to flip them for C, this patch repurpose these flags.

- if true, just set it.
- if false, just respect the value in clang.

this would allow us to keep flags on for C++, and optionally flip them on for C.

[flang] Make flang build compatible with LLVM dylib

Harmonize usage of LLVM components througout Flang.

Explicit LLVM Libs where used across several CMakeFIles, which led to
incompatibilities with LLVM shlibs.
Fortunately, the LLVM component system can be relied on to harmoniously handle
both cases.

[lldb-server][linux] Add ability to allocate memory

This patch adds support for the _M and _m gdb-remote packets, which
(de)allocate memory in the inferior. This works by "injecting" a
m(un)map syscall into the inferior. This consists of:
- finding an executable page of memory
- writing the syscall opcode to it
- setting up registers according to the os syscall convention
- single stepping over the syscall

The advantage of this approach over calling the mmap function is that
this works even in case the mmap function is buggy or unavailable. The
disadvantage is it is more platform-dependent, which is why this patch
only works on X86 (_32 and _64) right now. Adding support for other
linux architectures should be easy and consist of defining the
appropriate syscall constants. Adding support for other OSes depends on
the its ability to do a similar trick.

Revert "Reland "[SCEV] Model ptrtoint(SCEVUnknown) cast not as unknown, but as zext/trunc/self of SCEVUnknown"" and it's follow-ups

While we haven't encountered an earth-shattering problem with this yet,
by now it is pretty evident that trying to model the ptr->int cast
implicitly leads to having to update every single place that assumed
no such cast could be needed. That is of course the wrong approach.

Let's back this out, and re-attempt with some another approach,
possibly one originally suggested by Eli Friedman in
which should hopefully spare us this pain and more.

This reverts commits 1fb610429308a7c29c5065f5cc35dcc3fd69c8b1,

I've kept&improved the tests though.

[DebugInstrRef] Create DBG_INSTR_REFs in SelectionDAG

When given the -experimental-debug-variable-locations option (via -Xclang
or to llc), have SelectionDAG generate DBG_INSTR_REF instructions instead
of DBG_VALUE. For now, this only happens in a limited circumstance: when
the value referred to is not a PHI and is defined in the current block.
Other situations introduce interesting problems, addresed in later patches.

Practically, this patch hooks into InstrEmitter and if it can find a
defining instruction for a value, gives it an instruction number, and
points the DBG_INSTR_REF at that <instr, operand> pair.
