[X86] Change the IR sequence for _mm_storeh_pi and _mm_storel_pi to perform the store as a <2 x float> instead of i64.

This is similar to what we do for loadl_pi and loadh_pi.

llvm-svn: 365669

[X86] Add guards to some of the x86 intrinsic tests to skip 64-bit mode only intrinsics when compiled for 32-bit mode.

All the command lines are for 64-bit mode, but sometimes I compile
the tests in 32-bit mode to see what assembly we get and we need
to skip these to do that.

Summary:
While investigating breakages caused by D63110, I noticed we were
building the short options strings in three places. Some of them used a
leading ':' to detect missing arguments, and some didn't. This was the
indirect cause of D63110. Here, I move the common code into a utility
function.

Also, unify the code which appends the sentinel value at the end of the
option vector, and make it harder for users to pass invalid argc-argv
combos to getopt (another component of D63110) by having the
OptionParser::Parse function take a (Mutable)ArrayRef.

This unification has uncovered that we don't handle missing arguments
while building aliases, However, it's not possible to write an effective
test for this, as right now it is not possible to return an error out of
the alias parsing code (which means we are printing the generic
"failure" message even after this patch).

We've already checked that each element is the correct contributory size for VT when we inspect the elements for Undef/Zero/Load.

This renames the type so it doesn't sound like its based off the load size - as we're moving towards supporting combining loads of different sizes.

With this style, a compressed section is indicated by a "z" in the section
name, instead of a section header flag. This patch consists of two small tweaks:
- use an llvm Decompressor method in order to properly detect compressed sections
- make sure we recognise .zdebug_info (and friends) when classifying section types.

Expected types in EXPECT calls. While static_cast is used in all cases
but one, bool provides more clarity and makes more sense as a new

Indeed, not all of these patterns are canonical.
But since this fold will only produce a single instruction
i'm really interested in handling even uncanonical patterns.

Other than these 6 patterns, i can't think of any other
reasonable variants right now, although i'm sure they exist.

For now let's start with patterns where both shift amounts are variable,
with trivial constant "offset" between them, since i believe this is
both simplest to handle and i think this is most common.
But again, there are likely other variants where we could use
ValueTracking/ConstantRange to handle more cases.

Transform
pow(C,x) 

To
exp2(log2(C)*x) 

if C > 0, C != inf, C != NaN (and C is not power of 2, since we have some fold for such case already).

log(C) is folded by the compiler and exp2 is much faster to compute than pow.

D64130 introduced a bug described in the following message:
https://reviews.llvm.org/D64130#1571560

The problem can happen with the following script:

SECTIONS {
  .out : {
...
   FILL(0x10101010)
   *(.aaa)
...
}

The current code tries to read (0x10101010) as an expression and
does not break when meets *, what results in a script parsing error.

In this patch, I verify that FILL command's expression always wrapped in ().
And at the same time =<fillexp> expression can be both wrapped or unwrapped.
I checked it matches to bfd/gold.
