ab043ff680 [opaque pointer type] Add textual IR support for explicit type parameter to load instruction
Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

import fileinput
import sys
import re

pat = re.compile(r"((?:=|:|^)\s*load (?:atomic )?(?:volatile )?(.*?))(| addrspace\(\d+\) *)\*($| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$)")

for line in sys.stdin:
  sys.stdout.write(re.sub(pat, r"\1, \2\3*\4", line))

a0cd02ace9 [mips] Promote i32 arguments to i64 for the N32/N64 ABI and fix <64-bit structs...
Summary:
... and after all that refactoring, it's possible to distinguish softfloat
floating point values from integers so this patch no longer breaks softfloat to
do it.

Remove direct handling of i32's in the N32/N64 ABI by promoting them to
i64. This more closely reflects the ABI documentation and also fixes
problems with stack arguments on big-endian targets.

We now rely on signext/zeroext annotations (already generated by clang) and
the Assert[SZ]ext nodes to avoid the introduction of unnecessary sign/zero
extends.

It was not possible to convert three tests to use signext/zeroext. These tests
are bswap.ll, ctlz-v.ll, ctlz-v.ll. It's not possible to put signext on a
vector type so we just accept the sign extends here for now. These tests don't
pass the vectors the same way clang does (clang puts multiple elements in the
same argument, these map 1 element to 1 argument) so we don't need to worry too
much about it.

With this patch, all known N32/N64 bugs should be fixed and we now pass the
first 10,000 tests generated by ABITest.py.

6822f77667 [mips][mips64r6] Replace m[tf]hi, m[tf]lo, mult, multu, dmult, dmultu, div, ddiv, divu, ddivu for MIPS32r6/MIPS64.
Summary:
The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have
been removed and replaced with GPR-based equivalents. For example:
  div $1, $2
  mflo $3
is now:
  div $3, $1, $2

This patch disables the accumulator-based multiplies and divides for
MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead.

Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the
behaviour of the function.

MipsDelaySlotFiller now invalidates the liveness information when moving
instructions to the delay slot. Without this, divrem.ll will abort since
%GP ends up used before it is defined.

ff992a6f20 [mips][mips64r6] Improve tests affected by the changes to multiplies and divides
Summary:
MIPS32r6/MIPS64r6 support has not been added yet.

inlineasm-cnstrnt-reg.ll:
  Explicitly specify the CPU since it will not work on MIPS32r6/MIPS64r6
  when -integrated-as is the default. We can't change the mnemonic since the
  LO register is an implicit def of mtlo and MIPS32r6/MIPS64r6 has no
  instructions that use LO.

2008-08-01-AsmInline.ll:
  Explicitly specify the CPU since MIPS32r6/MIPS64r6 will correctly emit
  different code and this is a regression test.

mips64instrs.ll and mips64muldiv.ll
  Check registers and the way the multiply is used in m1

divrem.ll
  Check registers and use multiple filecheck prefixes to limit redundancy

7e501cf4c3 Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.
This update was done with the following bash script:

  find test/CodeGen -name "*.ll" | \
  while read NAME; do
    echo "$NAME"
    if ! grep -q "^; *RUN: *llc.*debug" $NAME; then
      TEMP=`mktemp -t temp`
