    • Optimize Swissmap Match on Arm. · 039d70f6 
      Currently we require only a single bit to be set in each abstract bit for iterable bitmasks. However, in most cases, where we have a single match, or no matches in a group, iteration is not needed. We move the masking to the iteration function instead of having it as a requirement for iterable Bitmask construction.

This is 4-8% faster for Find and Insert operations.

This can hurt performance if we need to iterate many times (there are many matches in the same Group), however this is unlikely, even if we assume the table is completely full.

If there are 0 or 1 matches in a group, or the first match is the correct item we are looking for, we save 1 instruction/cycle (most cases)
If there are 2 matches in a group, and the first is a false positive, this is neutral (< 3%)
If there are more than 2 matches in a group and the first two are false positives, this can be slower by 1 cycle/instruction per additional iteration (< 0.1%)

No change to x86.

    • PR #1498: Fix order of link options in pkg-config files · 407f2fdd 
      Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1498

In Windows, a few libraries (`dbghelp`, `advapi32`, and `bcrypt`) are added via link options. However, the .pc files produced for pkg-config erroneously include them before the abseil libraries. This can cause undefined references when trying to build against abseil.

This commit swaps the order and adds the custom link options after the abseil dependencies. The following is a list of `.pc` files affected by this and the additional link options used:

* all: `-L${libdir}`
*  `absl_base.pc`: `-ladvapi32`
* `absl_random_internal_seed_material.pc`: `-lbcrypt`
* `absl_symbolize.pc`: `-ldbghelp`

Closes https://github.com/abseil/abseil-cpp/issues/1497
