Yangyu Chen bb5a9dc247 Support jemalloc as the default allocator on Linux (#7250)
Add jemalloc as an alternative malloc implementation for the Verilator
binary. When both tcmalloc and jemalloc are available, jemalloc is
preferred due to its better performance on RTLMeter.

The new --enable-jemalloc flag (default=check) mirrors the existing
--enable-tcmalloc behavior: auto-detected at configure time, supports
both static and dynamic linking, and is disabled when --enable-dev-asan
is active.

via a typedef. Keep them as a single signal instead.

Rahul Behl 2046879beb V3Randomize: Fix dist operator inside ConstraintIf blocks (#7221) (#7224)
The lowerDistConstraints() function was not recursing into ConstraintIf
nodes, causing dist operators inside if-else blocks to remain unlowered
and trigger an internal error when ConstraintExprVisitor encountered them.

Fix by adding recursive handling of ConstraintIf nodes in lowerDistConstraints:
- Check for AstConstraintIf nodes before AstConstraintExpr
- Recursively process thensp() and elsesp() branches
- This ensures all dist operators are lowered regardless of nesting

Test case: t_randomize_dist_conditional.v demonstrates conditional dist:
    constraint c {
      if (randd) {
        x dist { 8'd0 := 1, 8'd255 := 3 };  // 25% / 75%
      } else {
        x dist { 8'd0 := 3, 8'd255 := 1 };  // 75% / 25%
      }
    }

Fixes #7221
