-----------
[Build Speed] 2s speedup in clean WTF+bmalloc build
https://bugs.webkit.org/show_bug.cgi?id=312108
rdar://174616734
Reviewed by Marcus Plutowski.
Reduced bmalloc compilation overhead.
1. In the WTF configuration where we inline most of bmalloc into
FastMalloc, #ifdef out the separate out of line implementation in bmalloc. It's
unused.
2. Merge Gigacage.h/.cpp and FastMalloc.h/.cpp because it's expensive to include
all the bmalloc inlines separately, and Gigacage is merged with malloc inside
bmalloc anyway.
3. Don't #include all of bmalloc.h in Threading.h just to expose a single QoS
API. Instead expose the API through FastMalloc, which already includes those
headers in its implementation.
