[ARM] [MC] Add support for writing ARM WinEH unwind info
This includes .seh_* directives for generating it from assembly.
It is designed fairly similarly to the ARM64 handling.
For .seh_handler directives, such as
".seh_handler __C_specific_handler, @except" (which is supported
on x86_64 and aarch64 so far), the "@except" bit doesn't work in
ARM assembly, as '@' is used as a comment character (on all current
platforms).
Allow using '%' instead of '@' for this purpose. This convention
is used by GAS in similar contexts already,
e.g. [1]:
Note on targets where the @ character is the start of a comment
(eg ARM) then another character is used instead. For example the
ARM port uses the % character.
In practice, this unfortunately means that all such .seh_handler
directives will need ifdefs for ARM.
Contrary to ARM64, on ARM, it's quite common that we can't evaluate
e.g. the function length at this point, due to instructions whose
length is finalized later. (Also, inline jump tables end with
a ".p2align 1".)
If unable to to evaluate the function length immediately, emit
it as an MCExpr instead. If we'd implement splitting the unwind
info for a function (which isn't implemented for ARM64 yet either),
we wouldn't know whether we need to split it though.
Avoid calling getFrameIndexOffset() on an unset
FuncInfo.UnwindHelpFrameIdx, to avoid triggering asserts in the
preexisting testcase CodeGen/ARM/Windows/wineh-basic.ll. (Once
MSVC exception handling is fully implemented, those changes
can be reverted.)

Summary:
While disassembling instructions, we need to replace certain immediate

have multiple immediate operands and up to two relocations against
them. Thus, correctly matching a relocation to an operand is not
always possible without knowing the operand offset within the
instruction.
Luckily, LLVM provides an interface for passing the required info from
the disassembler via a virtual MCSymbolizer class. Creating a
target-specific version allows a precise matching of relocations to
operands.

[LoopIdiom] Fix bailout for aliasing in memcpy transform.
Commit
dd5991cc modified the aliasing checks here to allow transforming
a memcpy where the source and destination point into the same object.
However, the change accidentally made the code skip the alias check for
other operations in the loop.
Instead of completely skipping the alias check, just skip the check for
whether the memcpy aliases itself.

[mlir][sparse] Improving the FATAL macro
The previous macro definition using `{...}` would fail to compile when the callsite uses a semicolon followed by an else-statement (i.e., `if (...) FATAL(...); else ...;`). Replacing the simple braces with `do{...}while(0)` (n.b., semicolon not included in the macro definition) enables callsites to use the semicolon plus else-statement syntax without problems. The new definition now requires the semicolon at all callsites, but since it was already being called that way nothing changes.
