LLD needs them, and it's good to be able to print them properly when
our object dumpers encounter them.

The timestamp meant these files changed with each invocation of
relocs.py, confusing matters when we add relocations and need to
update the tests.

By default, LLVM uses the "C" calling convention for all runtime
library functions. The half-precision FP conversion functions use the
soft-float calling convention, and are needed for some targets which
use the hard-float convention by default, so must have their calling
convention explicitly set.

be propagated to all its users, and this propagation could increase the
probability of finding common subexpressions. If the COPY has only one user,
the COPY itself can be removed.

and the lattice will be updated to be a state other than "undefined". This
limiation could miss some opportunities of lowering "overdefined" to be an
even accurate value. So this patch ask the algorithm to try to lower the
lattice value again even if the value has been lowered to be "overdefined".

The ARM ARM states that CPSR may not be updated by a MUL in thumb mode. Due to
an ordering of Thumb 2 Size Reduction and If Conversion, we would end up
generating a THUMB MULS inside an IT block.
The If Conversion pass uses the TTI isPredicable method to ensure that it can
transform a Basic Block. However, because we only check for IT handling on
Thumb2 functions, we may miss some cases. Even then, it only validates that the
CPSR is not *live* rather than it is not accessed. This corrects the handling
for that particular case since the same restriction does not hold on the vast
majority of the instructions.
This does prevent the IfConversion optimization from kicking in in certain
cases, but generating correct code is more valuable. Addresses PR20555.

For ori, they are unsigned, for addi, signed. Create a new target
expression type to handle this and evaluate Fixups accordingly.

Remove the MinGW32 and Cygwin types from the OSType enumeration. These values
are represented via environments of Windows. It is a source of confusion and
needlessly clutters the code. The cost of doing this is that we must sink the
check for them into the normalization code path along with the spelling.
Addresses PR20592.

This removes the duplicate definition of GetXDataSection. This function is
available as a static method and is identical to the previous implementation.
This just cleans up the unnecessary duplication.

These tests were using SI-NOT: MOVREL to make sure concat vectors
weren't being lowered to stack loads and stores, but we are using
scratch buffers for the stack now instead of registers, so we need
to add an additional SI-NOT check for scratch buffers.
With this change I was able to uncover one broken test which will
be fixed in a future commit.
