[DAGCombiner] fold assertzexts separated by trunc If we have an AssertZext of a truncated value that has already been AssertZext'ed, we can assert on the wider source op to improve the zext-y knowledge: assert (trunc (assert X, i8) to iN), i1 --> trunc (assert X, i1) to iN This moves a fold from being Mips-specific to general combining, and x86 shows improvements.

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922

[opaque pointer type] Add textual IR support for explicit type parameter to gep operator Similar to gep (r230786) and load (r230794) changes. Similar migration script can be used to update test cases, which successfully migrated all of LLVM and Polly, but about 4 test cases needed manually changes in Clang.
