Existing DAG combine only handles conversions for FP_TO_SINT:
"{f32, f64} x { i32, i16 }"
This patch simplifies the code to handle:
"{ FP_TO_SINT, FP_TO_UINT } x { f64, f32 } x { i64, i32, i16, i8 }"

Some MIPS relocations depend on "gp" value. By default, this value has
0x7ff0 offset from a .got section. But relocatable files produced by a
compiler or a linker might redefine this default value and we have to
use it for a calculation of the relocation result. When we generate EXE
or DSO it's trivial. Generating a relocatable output is more difficult
case because the linker does calculate relocations in this case and
cannot store individual "gp" values used by each input object file.
As a workaround we add the "gp" value to the relocation addend.

Summary:
As discussed in D45931, currently, profiling output of clang-tidy is somewhat not great.
It outputs one profile at the end of the execution, and that profile contains the data
from the last TU that was processed. So if the tool run on multiple TU's, the data is
not accumulated, it is simply discarded.
It would be nice to improve this.
This differential is the first step - make this profiling info per-TU,
and output it after the tool has finished processing each TU.
In particular, when `ClangTidyASTConsumer` destructor runs.
Next step will be to add a CSV (JSON?) printer to store said profiles under user-specified directory prefix.

Patch https://reviews.llvm.org/D41445 changed the behaviour of 'isReg()'
to also return 'true' if the parsed register operand is a vector
register. Code in the AsmMatcher checks if a register is a subclass of the
expected register class. However, even though both parsed registers map
to the same physical register, the 'v' register is of kind 'NeonVector',
where 'q' is of type Scalar, where isSubclass() does not distinguish
between the two cases.
The solution is to use an AsmOperand instead of the register directly,
and use the PredicateMethod to distinguish the two operands.
This fixes for example:
ldr v0, [x0] // 'v0' is an invalid operand for this instruction
ldr q0, [x0] // valid

This is a fix for PR30290: by marking all byval stack slots as being aliased,
the instruction scheduler is more conservative about rescheduling memory
accesses to such stack slots as an LLVM Value* might alias it. This fixes
errors such as in the patched test case, where reads and writes to a data
structure are illegally mixed.
This could be fixed better in the future with better analysis for the
instruction scheduler to know what Values alias what stack slots.

Summary:
In formLCSSAForInstructions we speculatively add new PHI
nodes, that sometimes ends up without having any uses. It
has been discovered that sometimes an added PHI node can
appear as being unused in one iteration of the Worklist,
although it can end up being used by a PHI node added in
a later iteration. We now check, a second time, that the
PHI node still is unused before we remove it. This avoids
an assert about "Trying to remove a phi with uses." for the
added test case.

Summary:
... and fix one bug found this way. Currently, the test works not because
types are looked up correctly, but because by injecting local variables
we also materialize the types for Clang. If we disable the local variable
injection, then one check fails.
The reason of the failure is that FindTypes is run with max_matches==1
and this value is passed down to the symbol lookup functions. When the
search is performed only on the basename (like it's the case for an
entity defined in the root namespace), then the search will stop after
having found one match on the basename. But that match might be in a
namespace, we were really just looking up the basename in the accelerator
tables.
The solution is to not pass max_matches down, but to search without a
limit and let RemoveMismatchedTypes do its job afterwards. Note the
patch includes 2 hunks with the same change, but only the latter is
tested. I couldn't find a way to create a testcase for the other
branch of the if ('image lookup -t' allows me to get there, but it
only ever returns one type anyway).
