d3ac47f805 Reverse order of operands of address operand mem so that the base operand comes
before the offset. This change will enable simplification of function
MipsRegisterInfo::eliminateFrameIndex.

9194c6716b If known DebugLocs do not match then two DBG_VALUE machine instructions are not identical. For example,
DBG_VALUE 3.310000e+02, 0, !"ds"; dbg:sse.stepfft.c:138:18 @[ sse.stepfft.c:32:10 ]
        DBG_VALUE 3.310000e+02, 0, !"ds"; dbg:sse.stepfft.c:138:18 @[ sse.stepfft.c:31:10 ]

These two MIs represent identical value, 3.31...,  for one variable, ds, but they are not identical because the represent two separate instances of inlined variable "ds".

944520f38c Add functions 'hasPredecessor' and 'hasPredecessorHelper' to SDNode. The
hasPredecessorHelper function allows predecessors to be cached to speed up
repeated invocations. This fixes PR10186.

X.isPredecessorOf(Y) now just calls Y.hasPredecessor(X)

Y.hasPredecessor(X) calls Y.hasPredecessorHelper(X, Visited, Worklist) with
empty Visited and Worklist sets (i.e. no caching over invocations).

Y.hasPredecessorHelper(X, Visited, Worklist) caches search state in Visited
and Worklist to speed up repeated calls. The Visited set is searched for X
before going to the worklist to further search the DAG if necessary.

a38cfb2fce When tail-merging multiple blocks, make sure to correctly update the live-in list on the merged block to correctly account for the live-outs of all the predecessors. They might not be the same in all cases (the testcase I have involves a PHI node where one of the operands is an IMPLICIT_DEF).
Unfortunately, the testcase I have is large and confidential, so I don't have a test to commit at the moment; I'll see if I can come up with something smaller where this issue reproduces.

d1689ae4b1 Mark ARM pseudo-instructions as isPseudo.
This allows us to remove the (bogus and unneeded) encoding information from
the pseudo-instruction class definitions. All of the pseudos that haven't
been converted yet and still need encoding information instance from the normal
instruction classes and explicitly set isCodeGenOnly, and so are distinct
from this change.
