When the file isn't being built with subsections-via-symbols, symbol
differences involving non-local symbols can be resolved more aggressively.
Needed for gas compatibility.

Fix a bunch of SSE/AVX patterns to use proper memop types. In particular, not using integer loads other than v2i64/v4i64 since the others are all promoted.

generator to it. For non-bundle instructions, these behave exactly the same
as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the
bundled instructions has the property it would return true.
For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.

make CR spill and restore 64-bit clean (no functional change), and fix some other problems found with -verify-machineinstrs

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.

These fields are not used for anything yet.

The TokenAlias handling of data type suffices renders these unnecessary.

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

make the addend fixup code a bit more generic

Patch by Jack Carter.

llvm-svn: 145998

No functional change yet. Will be implementing range-checked immediates
for better diagnostics and disambiguation of instructions.

This caused more offset errors.

1. Added opcode BUNDLE
2. Taught MachineInstr class to deal with bundled MIs
3. Changed MachineBasicBlock iterator to skip over bundled MIs; added an iterator to walk all the MIs
4. Taught MachineBasicBlock methods about bundled MIs

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.

llvm-svn: 145971

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.
