Summary:
Currently FPOWI defaults to Legal and LegalizeDAG.cpp turns Legal into Expand for this opcode because Legal is a "lie".
This patch changes the default for this opcode to Expand and removes the hack from LegalizeDAG.cpp. It also removes all the code in the targets that set this opcode to Expand themselves since they can just rely on the default.

A suspended translation unit uses significantly less memory but on the
other side does not support any other calls than
clang_reparseTranslationUnit to resume it or
clang_disposeTranslationUnit to dispose it completely.
This helps IDEs to reduce the memory footprint. The data that is freed
by a call to clang_suspendTranslationUnit will be re-generated on the
next (re)parse anyway. Used with a preamble, this allows pretty fast
resumption of the translation unit for further use (compared to disposal
of the translation unit and a parse from scratch).

Previously, a preamble only included #if blocks (and friends like
ifdef) if there was a corresponding #endif before any declaration or
definition. The problem is that any header file that uses include guards
will not have a preamble generated, which can make code-completion very
slow.
To prevent errors about unbalanced preprocessor conditionals in the
preamble, and unbalanced preprocessor conditionals after a preamble
containing unfinished conditionals, the conditional stack is stored
in the pch file.
This fixes PR26045.

When there is a linker script with .ARM.exidx in the SECTIONS
command we must add the .ARM.exidx sentinel section to the
InputSectionDescriptions as well as to OutputSection::Sections.

everything away at -O0.
Sadly the overloading turned this into a big macro mess. Fixes PR33212.

This adds assembler / disassembler support for the decimal
floating-point instructions. Since LLVM does not yet have
support for decimal float types, these cannot be used for
codegen at this point.

This adds assembler / disassembler support for the hexadecimal
floating-point instructions. Since the Linux ABI does not use
any hex float data types, these are not useful for codegen.

The maximum alignment for ARM NEON data types should be 64-bits as specified
in ARM procedure call standard document Sec. A.2 Notes.
This patch fixes it from its current larger natural default values, except
for Android (so as not to break existing ABI).

The MC ConstantPool class uses a DenseMap to track generated constants, with
the int64_t value of the constant as the key. This fails when values of
0x7fffffffffffffff or 0x7ffffffffffffffe are inserted into the constant pool, as
these are sentinel values for DenseMap.
The fix is to use std::map instead, which doesn't use sentinel values.

I found that during visual inspection of code while wrote different patch.
Script in testcase probably have nothing common with real life, but
we segfault currently using it.
If output section is known NOBITS, there is no need to create
writers threads for doing nothing or proccess any filler logic that
is useless here. We can just early return, that is what this patch do.

While the following expression is handled fine:
PROVIDE_HIDDEN(newsym = oldsym + address);
The following expression triggers an error because the expression
is evaluated as absolute:
PROVIDE_HIDDEN(newsym = ALIGN(oldsym, CONSTANT(MAXPAGESIZE)) + address);
To avoid this error, we use late evaluation for ALIGN by making the
alignment an attribute of the expression itself.

from_address requires that the provided pointer refer to the suspended coroutine,
which doesn't have a type, or at least not one knowable by the user. Therefore
every use of `from_address` with a typed pointer is almost certainly a bug.
This behavior is a part of the TS specification, but hopefully it will be
in the future.
