Saleem Abdulrasool 6eae1e6bbf MC: loosen an overzealous assertion
Permit active macro expansions when terminating the assembler if there were
errors during the expansion.  This would only trigger on invalid input when
built with assertions.

Manuel Klimek 95403e6f60 Make the parent-map use significantly less memory.
On test files I ran this on, memory consumption overall went down from
2.5G to 2G, without performance regressions.
I also investigated making DynTypedNode by itself smaller (by pulling
out pointers for everything that doesn't fit in 8 bytes). This led to
another 200-300MB saved, but also introduced a significant regression in
performance due to the memory management overhead.

Daniel Sanders 3ea9274c87 [asm matcher] Fix incorrect assertion when there are exactly 32 SubtargetFeatures
Summary:
The minimal type needs to hold a value of '1ULL << 31' but
getMinimalTypeForRange() is called with a value of '1ULL << 32'.

This patch will also reduce the size of the matcher table when there are 8
or 16 SubtargetFeatures.

Also added a dump of the SubtargetFeatures to the -debug output and corrected getMinimalTypeInRange() to consider 0xffffffffull to be a 32-bit value.

The testcase is that no existing code is broken and that LLVM still successfully
compiles after adding MIPS64r6 CodeGen support.

Evgeniy Stepanov 208aae8ee0 [msan] Chained origins re-design.
Generalize StackDepot and create a new specialized instance of it to
efficiently (i.e. without duplicating stack trace data) store the
origin history tree.

This reduces memory usage for chained origins roughly by an order of
magnitude.

Most importantly, this new design allows us to put two limits on
stored history data (exposed in MSAN_OPTIONS) that help avoid
exponential growth in used memory on certain workloads.

See comments in lib/msan/msan_origin.h for more details.

Saleem Abdulrasool 8d60fdc50d ARM: correct bundle generation for MOV32T relocations
Although the previous code would construct a bundle and add the correct elements
to it, it would not finalise the bundle.  This resulted in the InternalRead
markers not being added to the MachineOperands nor, more importantly, the
externally visible defs to the bundle itself.  So, although the bundle was not
exposing the def, the generated code would be correct because there was no
optimisations being performed.  When optimisations were enabled, the post
register allocator would kick in, and the hazard recognizer would reorder
operations around the load which would define the value being operated upon.

Rather than manually constructing the bundle, simply construct and finalise the
bundle via the finaliseBundle call after both MIs have been emitted.  This
improves the code generation with optimisations where IMAGE_REL_ARM_MOV32T
relocations are emitted.

The changes to the other tests are the result of the bundle generation
preventing the scheduler from hoisting the moves across the loads.  The net
effect of the generated code is equivalent, but, is much more identical to what
is actually being lowered.
