cc7b5b71eb Do not try to rematerialize a value from a partial definition.

tomorrow.  <rdar://problem/10032939>

1eacb83316 Change ARM / Thumb2 addc / adde and subc / sube modeling to use physical 
register dependency (rather than glue them together). This is general
goodness as it gives scheduler more freedom. However it is motivated by
a nasty bug in isel.

When a i64 sub is expanded to subc + sube.
  libcall #1
     \
      \        subc 
       \       /  \
        \     /    \
         \   /    libcall #2
          sube

If the libcalls are not serialized (i.e. both have chains which are dag
entry), legalizer can serialize them in arbitrary orders. If it's
unlucky, it can force libcall #2 before libcall #1 in the above case.

  subc
   |
  libcall #2
   |
  libcall #1
   |
  sube

However since subc and sube are "glued" together, this ends up being a
cycle when the scheduler combine subc and sube as a single scheduling
unit.

The right solution is to fix LegalizeType too chains the libcalls together.
However, LegalizeType is not processing nodes in order so that's harder than
it should be. For now, the move to physical register dependency will do.

4d90e53381 Explicitly zero out parts of a vector which are required to be zero by the algorithm in LowerUINT_TO_FP_i32. This only has a substantial effect on the generated code when the input is extracted from a vector register; other ways of loading an i32 do the appropriate zeroing implicitly. Fixes PR10802.

f26343ced2 Fix a test that wasn't testing the right thing.

APFloat(const fltSemantics &, integerPart) constructor, and EXPECT_EQ was
