fb54afbcb8 Incremental big endian patch by Jack Carter.
These changes allow us to compile big endian from the command line for 32 bit
Mips targets. This patch will result in code and data actually being produced
in the correct endianess.

4211c196d4 Make sure ImmutableSet never inserts Tombstone/Entry into DenseMap.
ImmutAVLTree uses random unsigned values as keys into a DenseMap,
which could possibly happen to be the same value as the Tombstone or
Entry keys in the DenseMap.

Test case is hard to come up with. We randomly get failures on the
internal static analyzer bot, which most likely hits this issue
(hard to be 100% sure without the full stack).

5069b21b45 RuntimeDyldMachO has the ability to keep track of
relocations (i.e., pieces of data whose addresses
are referred to elsewhere in the binary image) and
update the references when the section containing
the relocations moves.  The way this works is that
there is a map from section IDs to lists of
relocations.

Because the relocations are associated with the
section containing the data being referred to, they
are updated only when the target moves.  However,
many data references are relative and also depend
on the location of the referrer.

To solve this problem, I introduced a new data
structure, Referrer, which simply contains the
section being referred to and the index of the
relocation in that section.  These referrers are
associated with the source containing the
reference that needs to be updated, so now
regardless of which end of the relocation moves,
the relocation will now be updated correctly.

aaa1e2f820 Require a base pointer for stack realignment when SP may vary dynamically.
ARMBaseRegisterInfo::canRealignStack was checking for variable-sized objects
but not for stack adjustments around calls.  Use hasReservedCallFrame() to
check for both.  The hasBasePointer function was already correctly checking
both conditions, so the effect of this was that a base pointer would be used
without checking whether the base pointer register could be reserved. I don't
have a small testcase for this.

21e42d0ea5 It's possible to have a constant expression who's size is quite big (e.g.,
i128). In that case, we may not be able to print out the MCExpr as an
expression. For instance, we could have an MCExpr like this:

    0xBEEF0000BEEF0000 | (0xBEEF0000BEEF0000 << 64)

The MCExpr printer handles sizes up to 64-bits, but this expression would
require 128-bits. In this situation, try to evaluate the constant expression and
emit that as the value into 64-bit chunks.

89f4e6639d Remove code that prevented lowering shuffles if they are used by load and themselves used by a extract_vector_elt. This was done to allow the DAG combiner to collapse to a single element load. Unfortunately, sometimes the extract_vector_elt would disappear before DAG combine could do the transformation leaving a vector_shuffle that isel couldn't handle. New code lets the shuffle be converted to a target specific node, but then adds a combine routine that can convert target specific nodes back to vector_shuffles if the folding criteria are met.
