libstdc++'s <cstdalign> #includes <stdalign.h> and expects it to guard against

the C++11 standard is broken in various ways here (it refers to the contents
of <stdalign.h> in C99, where that header did not exist, and doesn't mention
the alignas macro at all), but we do our best to do what it intended.

Mips specific standalone assembler addressing mode %hi and %lo.
The constructs %hi() and %lo() represent the high and low 16
bits of the address.
Because the 16 bit offset field of an LW instruction is
interpreted as signed, if bit 15 of the low part is 1 then the
low part will act as a negative and 1 needs to be added to the
high part.

[analyzer] Tighten up safety in the use of lazy bindings.
- When deciding if we can reuse a lazy binding, make sure to check if there
are additional bindings in the sub-region.
- When reading from a lazy binding, don't accidentally strip off casts or
base object regions. This slows down lazy binding reading a bit but is
necessary for type sanity when treating one class as another.
A bit of minor refactoring allowed these two checks to be unified in a nice
early-return-using helper function.

If you say

this is misleading and should probably hint that there is no process. Adding this flag makes sure that we get:

PPCDAGToDAGISel::PostprocessISelDAG()
This patch implements the PPCDAGToDAGISel::PostprocessISelDAG virtual
method to perform post-selection peephole optimizations on the DAG
representation.
One optimization is implemented here: folds to clean up complex
addressing expressions for thread-local storage and medium code
model. It will also be useful for large code model sequences when
those are added later. I originally thought about doing this on the
MI representation prior to register assignment, but it's difficult to
do effective global dead code elimination at that point. DCE is
trivial on the DAG representation.
A typical example of a candidate code sequence in assembly:
addis 3, 2, globalvar@toc@ha
addi 3, 3, globalvar@toc@l
lwz 5, 0(3)
When the final instruction is a load or store with an immediate offset
of zero, the offset from the add-immediate can replace the zero,
provided the relocation information is carried along:
addis 3, 2, globalvar@toc@ha
lwz 5, globalvar@toc@l(3)
Since the addi can in general have multiple uses, we need to only
delete the instruction when the last use is removed.
