2f0e1e182f Eliminate delta argument from AdjustBBOffsetsAfter. 
The block offset can be computed from the previous block. That is more
robust than keeping track of a delta.

Eliminate one redundant AdjustBBOffsetsAfter call.

Data type suffix aliasing. Previously handled via lots of instruction
aliases. Cleanup of those forthcoming.

14e284f16a Extend AsmMatcher token literal matching to allow aliasing. 
For example, ARM allows:
    vmov.u32 s4, #0  -> vmov.i32, #0
'u32' is a more specific designator for the 32-bit integer type specifier
and is legal for any instruction which accepts 'i32' as a datatype suffix.

We want to say,
    def : TokenAlias<".u32", ".i32">;

This works by marking the match class of 'From' as a subclass of the
match class of 'To'.

c5e1f4a242 Use conservative size estimate for tBR_JTr. 
This pseudo-instruction contains a .align directive in its expansion, so
the total size may vary by 2 bytes.

It is too difficult to accurately keep track of this alignment
directive, just use the worst-case size instead.

e757462141 Remove alignment from deserted constant islands. 
ARMConstantIslandPass may sometimes leave empty constant islands behind
(it really shouldn't). Remove the alignment from the empty islands so
the size calculations are still correct.

This should fix the many Thumb1 assembler errors in the nightly test
suite.

The reduced test case for this problem is way too big. That is to be
expected for ARMConstantIslandPass bugs.

7df1659ad7 Simplify common predecessor finding. 
- Walking over pred_begin/pred_end is an expensive operation.
- PHINodes contain a value for each predecessor anyway.
- While it may look like we used to save a few iterations with the set,
  be aware that getIncomingValueForBlock does a linear search on
  the values of the phi node.
- Another -5% on ARMDisassembler.cpp (Release build). This was the last
  entry in the profile that was obviously wasting time.
