The main purpose is to create tests for minimal app (hello world and its variations, i.e. unicode used) distribution size metric.
Many platforms support distribution in compressed form via gzip. It would be nice to collect information on how much size is taken by the executional bundle for each platform at minimal edge case.
2 groups of tests are added:
1. We extend javascript backend size tests with gzip-enabled versions for all cases where an optimizing compiler is used (for now it is google closure compiler).
2. We add trivial hello world tests with gzip-enabled versions for all other platforms at CI pipeline where no external optimizing compiler is used.

- beef61351b240967b49169d27a9a19565cf3c4af enabled the use of
MO_Add/MO_Sub for 64-bit operations in the C and LLVM backends
- 6755d833af8c21bbad6585144b10e20ac4a0a1ab did the same for the x86 NCG
backend
However we store some literal values as `Int` in the compiler. As a
result, some Cmm optimizations transformed target 64-bit literals into
compiler `Int`. If the compiler is 32-bit, this leads to computing with
wrong literals (see #24893 and #24700).
This patch disables these Cmm optimizations for 32-bit compilers. This
is unsatisfying (optimizations shouldn't be compiler-word-size
dependent) but it fixes the bug and it makes the patch easy to backport.
A proper fix would be much more invasive but it shall be implemented in
the future.

Need to extend JSC externs with Emscripten RTS definitions to avoid
JSC_UNDEFINED_VARIABLE errors when linking without the emcc rts.
Fix #25138
Some recompilation avoidance tests now fail. This is tracked with the
other instances of this failure in #23013. My hunch is that they were
working by chance when we used the emcc linker.
