This reverts commit r271096, as reverting it broke even more buildbots!

But that also means I'll break on ARM again... :(

Centralize assertion.

The name was out of date at this point and it seems simple enough to
have in-line.

It was triggering an msan bot.

Revert "[IRPGO] Set the function entry count metadata."

This reverts commit r271090.

Revert "[IRPGO] Centralize the function attribute inliner hint logic. NFC."

This reverts commit r271089.

This keeps the logic in the same function.

Composing subreg_loreg with subreg_oveflow leads to strange results with
lane masks for register classes with subreg_loreg. In particular, dead
lane detection generates incorrect code.

[sanitizers] introduce a common run-time option dedup_token_length to help with report deduplication, off by default for now. See https://github.com/google/sanitizers/issues/684

This mostly makes sure that 3-vector dynamic inserts
and extracts are covered.

Summary:
Adds detection of large stack size rlimits (over 1 TB or unlimited), which
results in an mmap location that our shadow mapping does not support.  We
re-exec the application in this situation.  Adds a test of this behavior.

Adds general detection of mmap regions outside of our app regions.  In the
future we want to try to adaptively handle these but for now we abort.

Moves the existing Linux-specific mmap code into a platform-specific file
where the new rlimit code lives.

Remove broken patterns matching it. This was matching the
unsafe math pattern and expanding the fix for the buggy instruction
from the pattern. The problems are also on CI. Remove the workarounds
and only use fract with unsafe math or from the intrinsic.

Summary:
Unroll factor (Count) calculations moved to a new function.
Early exits on pragma and "-unroll-count" defined factor added.
New type of unrolling "Force" introduced (previously used implicitly).
New unroll preference "AllowRemainder" introduced and set "true" by default.
(should be set to false for architectures that suffers from it).

Summary:
GLIBC recently removed the incorrect `int isinf(double)` and `int isnan(double)` overloads in C++11 and greater. This causes previously `XFAIL: linux`  tests to start passing.

Since there is no longer a way to 'XFAIL' the tests I choose to simply tolerate this bug.
