Add test for r146163.

Many of the SSE patterns should not be selected when AVX is available. This led to the following code in X86Subtarget.cpp

  if (HasAVX)
    X86SSELevel = NoMMXSSE;

This is so patterns that are predicated on hasSSE3, etc. would not be selected when avx is available. Instead, the AVX variant is selected.
However, this breaks instructions which do not have AVX variants.

The right way to fix this is for the SSE but not-AVX patterns to predicate on something like hasSSE3() && !hasAVX().
Then we can take out the hack in X86Subtarget.cpp. Patterns which do not have AVX variants do not need to change.

However, we need to audit all the patterns before we make the change. This patch is workaround that fixes one specific case,
the prefetch instructions. rdar://10538297

Don't include alignment padding in BBInfo.Size.

Compute alignment padding before and after basic blocks dynamically.

Heed basic block alignment.

This simplifies bookkeeping because we don't have to constantly add and
remove padding from BBInfo.Size.  It also makes it possible to track the
extra known alignment bits we get after a tBR_JTr terminator and when
entering an aligned basic block.

This makes the ARMConstantIslandPass aware of aligned basic blocks.

It is tricky to model block alignment correctly when dealing with inline
assembly and tBR_JTr instructions that have variable size.  If inline
assembly turns out to be smaller than expected, that may cause following
alignment padding to be larger than expected.  This could cause constant
pool entries to move out of range.

To avoid that problem, we use the worst case alignment padding following
inline assembly. This may cause slightly suboptimal constant island
placement in aligned basic blocks following inline assembly.  Normal
functions should be unaffected.

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'.

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.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145971 91177308-0d34-0410-b5e6-96231b3b80d8

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.
